Rules for formulas

Mathematical formulas are programmed according to the following
rules:

Higher-level operations are performed first

1st calculation: 5 * 3 = 15
2nd calculation: 2 * 10 = 20
3rd calculation: 15 + 20 = 35

or

1st calculation: 10 squared = 100
2nd calculation: 3 to the power of 3 = 27
3rd calculation: 100 – 27 = 73

Distributive law
Law for calculating with parentheses

a * (b + c) = a * b + a * c

12

Q1 = 5 * 3 + 2 * 10 = 35

13

Q2 = SQ 10 - 3^3 = 73
