Question

Using the number line, match the following multiplications of two numbers:

• A. $6$
• B. $-9$
• C. $12$
• D. $8$

Answer 1

As per the multiplication on number line shown in the attached above figure:

$2\times 3\to$ $2$ times jumps in the right of $‘‘0"$ with an interval of $3\Rightarrow 6$;

$3\times (-3)\to$ $3$ times jumps in the left of $‘‘0"$ with an interval of $3\Rightarrow -9$;

$(-4)\times (-3)\to$ $4$ times jumps in the right of $‘‘0"$ with an interval of $3\Rightarrow 12$;

$(+4)\times (+2)\to$ $4$ times jumps in the right of $‘‘0"$ with an interval of $2\Rightarrow 8$.
