Rules for formulas
Mathematical formulas are programmed according to the following
rules:
Higher-level operations are performed first
1st calculation: 5 * 3 = 15
2ndcalculation: 2 * 10 = 20
3rdcalculation: 15 + 20 = 35
or
1st calculation: 10 squared = 100
2ndcalculation: 3 to the power of 3 = 27
3rdcalculation: 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
