The calculator accepts common multiplication symbols such as × and x, as well as the standard asterisk *. It also recognizes the division symbol ÷ and the slash /.
This makes the tool flexible for users who want to enter calculations in a familiar mathematical format.
How to Use the Chegg Calculator
Using the calculator is straightforward. You only need to enter the expression you want to solve.
Step 1: Enter Your Calculation
Start by entering your mathematical expression in the Enter Calculation field.
For example:
25 + 15 × 2
You can also enter more complex expressions such as:
(25 + 15) × 2 – 10
The calculator accepts numbers, decimal values, mathematical operators, parentheses, percentages, and powers.
Step 2: Use the Quick Buttons
The calculator provides several quick-entry buttons:
- ( for opening parentheses
- ) for closing parentheses
- ^ for powers or exponents
- % for percentages
- C for clearing the expression
These buttons are particularly useful when you do not want to type mathematical symbols manually.
Step 3: Check the Expression
Before calculating, review the expression carefully. Make sure parentheses are properly paired and that operators are placed correctly.
For example:
(20 + 10) × 3
has matching opening and closing parentheses.
Step 4: Click Calculate
Select the Calculate button after entering the expression.
The calculator evaluates the expression and displays the result.
Step 5: Review the Answer
The result appears in the answer field and is also shown in the results section.
The calculator displays both:

Answer: The calculated result.
This makes it easier to confirm which expression produced the displayed answer.
Step 6: Clear or Reset
If you want to remove the current calculation, use the C button.
If you want to start completely over, use the Reset button.
Mathematical Operations Supported
The calculator is designed for everyday arithmetic and expression evaluation.
Addition
Addition uses the + symbol.
Example:
25 + 35 = 60
This is useful for combining quantities, prices, scores, measurements, and other numerical values.
Subtraction
Subtraction uses the – symbol.
Example:
100 – 35 = 65
Negative results are also supported.
Multiplication
Multiplication can be represented with an asterisk, the multiplication symbol, or the letter x.
Examples include:
8 × 7
8 * 7
8 x 7
All represent multiplication.
Division
Division can be entered using / or ÷.
For example:
100 ÷ 4 = 25
or:
100 / 4 = 25
The calculator also prevents division by zero, which is mathematically undefined.
Parentheses
Parentheses allow you to control which calculation is performed first.
For example:
(10 + 5) × 2 = 30
Without parentheses:
10 + 5 × 2 = 20
The results differ because multiplication is performed before addition under the standard order of operations.
Exponents
The ^ symbol is used to represent powers.
For example:
5^2 = 25
This means 5 is multiplied by itself two times.
Another example is:
2^3 = 8
because:
2 × 2 × 2 = 8
Percentages
The calculator also supports percentage expressions.
For example:
25%
represents:
25 ÷ 100 = 0.25
Therefore:
200 × 25% = 50
Percentages can be useful for calculating discounts, increases, proportions, and other everyday numerical relationships.
Formula and Calculation Method Explained
The calculator does not rely on one single formula. Instead, it evaluates the mathematical expression you provide according to standard arithmetic rules.
A simple expression might be:
[
a+b
]
while a more complex expression could be:
[
(a+b)\times c-d
]
The exact calculation depends on the numbers and operators entered.
Order of Operations
The most important principle for combined calculations is the order of operations.
A common way to remember this is PEMDAS:
- P = Parentheses
- E = Exponents
- M = Multiplication
- D = Division
- A = Addition
- S = Subtraction
Multiplication and division are generally evaluated from left to right, as are addition and subtraction.
For example:
[
10+5\times2
]
Multiplication comes first:
[
5\times2=10
]
Then:
[
10+10=20
]
So the answer is:
20
However:
[
(10+5)\times2
]
requires the parentheses to be evaluated first:
[
10+5=15
]
Then:
[
15\times2=30
]
The answer is therefore:
30
Percentage Calculation Explained
A percentage represents a portion out of 100.
The general conversion is:
[
Percentage = \frac{Number}{100}
]
For example:
[
20%=\frac{20}{100}=0.20
]
If you want to calculate 20% of 150:
[
150\times0.20=30
]
Therefore:
20% of 150 = 30
The calculator converts a percentage value into its decimal equivalent during evaluation.
Exponent Formula Explained
An exponent indicates repeated multiplication.
The basic formula is:
[
a^n
]
where:
- a is the base
- n is the exponent
For example:
[
3^4=3\times3\times3\times3
]
Therefore:
[
3^4=81
]
Another example:
[
10^2=100
]
Exponents are useful in mathematics, science, finance, engineering, and many other fields.
Chegg Calculator Examples
Example 1: Basic Arithmetic
Suppose you want to calculate:
45 + 25 – 10
First add:
[
45+25=70
]
Then subtract:
[
70-10=60
]
Answer: 60
Example 2: Multiplication and Addition
Calculate:
10 + 8 × 5
Multiplication comes first:
[
8\times5=40
]
Then:
[
10+40=50
]
Answer: 50
This example demonstrates why entering a complete expression into a calculator can help prevent order-of-operation mistakes.
Example 3: Parentheses
Calculate:
(10 + 8) × 5
First:
[
10+8=18
]
Then:
[
18\times5=90
]
Answer: 90
Notice that this result is different from the previous example because the parentheses change the order of calculation.
Example 4: Percentage
Calculate:
500 × 15%
Convert 15% to a decimal:
[
15%=0.15
]
Then:
[
500\times0.15=75
]
Answer: 75
This could represent 15% of a $500 amount, a 15% allocation, or another percentage-based calculation.
Example 5: Exponent
Calculate:
4^3
This means:
[
4\times4\times4
]
Therefore:
[
4^3=64
]
Answer: 64
Example 6: Combined Expression
Consider:
(20 + 10) × 3 – 15
First calculate the parentheses:
[
20+10=30
]
Then multiply:
[
30\times3=90
]
Finally subtract:
[
90-15=75
]
Answer: 75
This type of combined expression is exactly where an expression calculator can be especially useful.

Tips for Entering Accurate Calculations
Use Parentheses When Necessary
If a particular portion of an expression must be calculated first, use parentheses.
For example:
(50 + 25) × 2
is different from:
50 + 25 × 2
Check Negative Numbers
When working with negative values, use parentheses when they make the intended calculation clearer.
For example:
(-5) × 4
clearly indicates that the entire value -5 is being multiplied by 4.
Avoid Unnecessary Symbols
Make sure your expression contains valid numbers and operators. Typing unrelated letters or unsupported mathematical notation can cause the calculation to be rejected.
Check Percentages
Remember that 10% is equivalent to 0.10, not 10 when used as a numerical fraction.
Break Down Complex Problems
For particularly complicated mathematical problems, solve and verify smaller sections individually before combining them into a final expression.
Common Calculation Mistakes
Even simple arithmetic can produce incorrect answers when the expression is entered incorrectly.
One common mistake is ignoring the order of operations. For example, treating:
10 + 5 × 2
as:
(10 + 5) × 2
will produce the wrong result.
Another common mistake is entering the wrong percentage. For instance, 25% should be represented as 0.25 when thinking about its decimal equivalent.
Users should also make sure parentheses are properly matched. An opening parenthesis should have a corresponding closing parenthesis.
Finally, division by zero should always be avoided because it is undefined.
