Free Simplification & Approximation Practice Questions & Tips

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
