The acronym stands for B – Brackets, O – Order of powers, D – Division,
M – Multiplication, A – Addition, and S – Subtraction.
Step 1: 18 – 6 = 12,
Step 2: 7 x 6 = 42,
Step 3: 42 – 12 = 30.

Question 47.
21 ÷ (2 + 5) × 12 – 8
28,

Explanation:
According to the order of operations, there is a particular sequence which we need to follow,
on each operator while solving the given mathematical expression we apply BODMAS rule.
BODMAS is the elementary rule for the order of operation of the Binary operations.
The acronym stands for B – Brackets, O – Order of powers, D – Division,
M – Multiplication, A – Addition, and S – Subtraction.
Step 1: 2 + 5 = 7,
Step 2: 21 ÷ 7 = 3,
Step 3: 3 x 12 = 36,
Step 4: 36 – 8 = 28.

Simplify. Record each step.

Example
{50 – [13 – (8 + 3)]} ÷ 4 = 12
Step 1 8 + 3
Step 2 13 – 11 = 2
Step 3 50 – 2 = 48</>
Step 4 48 ÷ 4 = 12
