Question

Multiplication is repeated ____ ​

Answer 1

Answer:

Multiplication is repeated addition.

Step-by-step explanation:

Multiplication of natural numbers can be said as repeated addition because we get the same result.

For example,

If someone says 7 times 3 this means,

adding

3 + 3 + 3 + 3 + 3 + 3 + 3 = 21

Which is the same as,

$3\times 7 =$ 21

But for the multiplication of fractions, we can't say the same.

For example -

$\frac{3}{4} \times\frac{5}{2}$

If we say 3/4 times 5/2 this doesn't make sense when we say adding 5/2 up to 3/4 times.

This can be explained in another way like adding numerators and denominators separately.

$\frac{3\times5}{4\times2} = \frac{15}{8}$

$\frac{5+5+5}{2+2+2+2} = \frac{15}{8}$

In the case of negative numbers, we cannot say the same too. We can take the negative sign outside and show it.

$3\times(-5)$ = -15

Now taking minus outside,

$-(3\times5) = -(5+5+5+) = -15$

So we can say that multiplication is repeated addition.
