Rules for formulas
Mathematical formulas are programmed according to the following
rules:
Higher-level operations are performed first
1. Calculation step 5 * 3 = 15
2. Calculation step 2 * 10 = 20
3. Calculation step 15 + 20 = 35
or
1. Calculation step 10 squared = 100
2. Calculation step 3 to the third power = 27
3. Calculation step 100 –27 = 73
Distributive 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
