Question

Subtract the following and verify how it came

-84 from -107

Answer 1

-84 is to be substracted from -107
we can write it as
(-84) - (-107)
We know that two negatives will combine to form a positive
Therefore
It becomes -84+107
Now substract the small number from the large and give answer, the sign of the large number
That is substract 84 from 107
That is 23
Now give 23 the sign of large number, that is the sign of 107 that is +ve(positive) sign.
Hence the answer is +23
