Consider this example:
Find the value of the given expression:
21.5 of 12 ÷ 23 – 184 + 15 × 12 – (19.25 × 16)
Solution:
Step 1: First, we solve the expression within the brackets.
So, 21.5 of 12 ÷ 23 – 184 + 15 × 12 – (19.25 × 16) = 21.5 of 12 ÷ 23 – 184 + 15 × 12 – 308
Step 2: Next, we calculate the power if any, and terms which are linked by the word “of”
So, 21.5 of 12 ÷ 23 – 184 + 15 × 12 – 308 = 258 ÷ 8 – 184 + 15 × 12 – 308
Step 3: We calculate the division operations
258 ÷ 8 – 184 + 15 × 12 – 308 = 32.25 – 184 + 15 × 12 – 308

Step 4: We calculate the multiplication operations
32.25 – 184 + 15 × 12 – 308 = 32.25 – 184 + 180 – 308
Step 5: We calculate the addition operations
32.25 – 184 + 180 – 308 = 212.25 – 184 – 308
Step 6: At last, we calculate the subtraction operations
212.25 – 184 – 308 = -279.75
