Question

What is the remainder of 124 divided by 18?

Answer 1

It is `124/18=6*18+16` hence the remainder is `16`

Answer 2

The answer is `16` or `-2`. Both are the same thing.

Explanation:

You have to use Euclid's Division lemma.
It states that Dividend `=` Divisor `xx` Quotient `+` Remainder.
Where Remainder `<` Divisor.

Apply this and your question. You will get

124 `=` 18`xx` 6 + 16
OR
124 `=` 18`xx`7 `-` 2

So remainder is `16` or `-2`.
