Represent the following on number line: 2 × 4

Given, 2 × 4 . We know that, multiplication is the repeated addition of a number. So, 2 + 2 + 2 + 2 . Let us do this on number line: Draw a number line starting from zero. Move 2 steps four times from zero. We represent it by moving from 0 to 2 , 2 to 4 , 4 to 6 and 6 to 8 . Now, the final position from zero position gives the multiplication of the numbers. From the above: The distance of the final position from the zero position is 8 steps to the right of zero. ∴ 2 × 4 = 8 .

Represent the following on number line: 4 × 4

Given, 4 × 4 . We know that, multiplication is the repeated addition of a number. So, 4 + 4 + 4 + 4 . Let us do this on number line: Draw a number line starting from zero. Move 4 steps four times from zero. We represent it by moving from 0 to 4 , 4 to 8 , 8 to 12 and 12 to 16 . Now, the final position from zero position gives the multiplication of the numbers. From the above: The distance of the final position from the zero position is 16 steps to the right of zero. ∴ 4 × 4 = 16 .

Represent the following on number line: 6 × 2

Given, 6 × 2 . We know that, multiplication is the repeated addition of a number. So, 6 + 6 . Let us do this on number line: Draw a number line starting from zero. Move 6 steps two times from zero. We represent it by moving from 0 to 6 and 6 to 12 . Now, the final position from zero position gives the multiplication of the numbers. From the above: The distance of the final position from the zero position is 12 steps to the right of zero. ∴ 6 × 2 = 12 .
