Step-by-step explanation:
Given in the question an expression
5 + 10² – 3 × (12 – 8)
To solve this we will use DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction
Step 1
10²
100
5 + 100 – 3 × (12 – 8)
Step 2
(12 – 8)
(4)
5 + 100 – 3 × (4)
Step 2
3 × (4)
12
5 + 100 – 12
Step 3
5 + 100
105
105 - 12
Step 4
105 - 12
93
