Rules for formulas
Mathematical formulas are programmed according to the following
rules:
Higher-level operations are performed first
Example
12 Q1 = 5 * 3 + 2 * 10 = 35
1 Calculation 5 * 3 = 15
2 Calculation 2 * 10 = 20
3 Calculation 15 + 20 = 35
or
Example
13 Q2 = SQ 10 - 3^3 = 73
1 Calculation step 10 squared = 100
2 Calculation step 3 to the third power = 27
3 Calculation 100 – 27 = 73
Distributive law
Law of distribution with parentheses calculation
a * (b + c) = a * b + a * c
