How the Calculation Works (Simple Explanation)
A scientific calculator follows math rules step by step. It understands the order of operations, which means it solves parts of a problem in the correct order.
For example:
Problem:
5 + 3 × 2
The calculator does multiplication first:
3 × 2 = 6
Then it adds:
5 + 6 = 11
It also knows special math formulas.
Example with square root:
√49
The calculator finds the number that multiplies by itself to make 49.
That number is 7.
For trigonometry, it uses angle formulas that are commonly used in geometry and physics. You don’t need to remember the formulas. The calculator does the work for you.
