Worksheet on 21 Times Table

Example 1: Using the table of 21, evaluate 21 times 8 minus 9 plus 7.
Solution:
Let us express this statement mathematically.
From table of 21, 21 times 8 minus 9 plus 7 = 21 × 8  9 + 7
168  9 + 7 = 166
Hence, 21 times 8 minus 9 plus 7 is 166.

Example 2: Using 21 times table evaluate 5 plus 10 times 21 by 2.
Solution:
First, let us express the given statement mathematically.
5 plus 10 times 21 by 2 = 5 + 10 × 21 ÷ 2
5 + 210 ÷ 2 = 5 + 105 = 110
Hence, 5 plus 10 times 21 by 2 is 110.

Example 3: Find using the table of 21, 12 plus 21 times 0 minus 6
Solution:
12 + 21 × 0  6
12 + 0  6 = 12  6 = 6
