Step-by-Step Templates
Explore how the Math Calculator handles different types of inputs with step-by-step explanations:
Arithmetic Example
Input: 5 + 7
- Add the numbers:
5 + 7 = 12 - Result:
12
Algebra Example
Input: 2x + 5 = 13
- Subtract 5 from both sides:
2x = 13 - 5 - Simplify:
2x = 8 - Divide both sides by 2:
x = 8 ÷ 2 - Result:
x = 4
Mixed Example
Input: (5 + 3) * 2
- Simplify inside the parentheses:
5 + 3 = 8 - Multiply:
8 * 2 = 16 - Result:
16
Common Use Cases
Discover how the Math Calculator can assist in everyday scenarios:
Budgeting
Example: "How much is the total monthly expense?"
- Input your expenses:
1200 + 300 + 450 - Calculate the total:
1200 + 300 + 450 = 1950 - Result: Your total monthly expense is
1950.
Homework
Example: "Solve for x in basic algebra equations."
- Input the equation:
3x + 2 = 11 - Subtract 2 from both sides:
3x = 11 - 2 - Simplify:
3x = 9 - Divide both sides by 3:
x = 9 ÷ 3 - Result:
x = 3
Quick Math
Example: "Calculate average price, ratios, percentages."
- Input the prices:
(50 + 75 + 100) ÷ 3 - Calculate the total:
50 + 75 + 100 = 225 - Divide by the count:
225 ÷ 3 = 75 - Result: The average price is
75.
