Construct other times-tables for numbers from 11 to 20, as you did for 15.

Correct Answer

Numbers to construct: 11, 12, 13, 14, 16, 17, 18, 19, and 20

Method: Splitting method - split each number into 10 and the remaining part.

Example: Times-14: Split 14 as 10+410 + 4

3×14=3×10+3×43 \times 14 = 3 \times 10 + 3 \times 4 =30+12= 30 + 12 =42= 42
