Practical Examples
Example 1: Simple Expression
Expression: 3x + 2 (x = 5)
Evaluation:
- Substitute x:
3*5 + 2 - Multiply:
15 + 2 = 17
Output:17
Example 2: Expression with Multiple Variables
Expression: 2x + 3y - 4 (x = 3, y = 4)
Evaluation:
- Substitute variables:
2*3 + 3*4 - 4 - Multiply:
6 + 12 - 4 - Add/Subtract:
18 - 4 = 14
Output:14
Example 3: Complex Expression
Expression: (x^2 + y^2) / z (x = 4, y = 3, z = 5)
Evaluation:
- Substitute variables:
(4^2 + 3^2)/5 = (16 + 9)/5 - Add:
25/5 = 5
Output:5
These examples demonstrate how the calculator simplifies the evaluation process, saving time and reducing errors.
