21 Times Table Examples
-
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
-
Example 4: Charlie jogs 21 miles a week. Using the table of 21 calculate, how many miles does he jogs in 12 weeks?
Solution:
Using the table of 21, in 12 weeks he jogs 12 times 21.
i.e. 12 × 21= 252 miles
Therefore Charlie jogs 252 miles in 12 weeks.

Example 5: Mia plans 3 cupcakes per guest, and she knows 21 guests are visiting her party that evening. 4 guests did not turn up. Using 21 times table find how many cupcakes will be served now?
Solution:
Let us express this mathematically. 3 times 21 minus 3 times 4
Using the table of 21, 3 cupcakes times 21 guests = 3 × 21= 63 and 3 cupcakes times 4 guests = 3 × 4 = 12
i.e. 63 - 12 = 51
Therefore 51 cupcakes will be served now.
