Answer 2

Given:

i) subtract $-50 \ from\ 30$

ii) subtract $50 \ from\ -40$

We have to solve the above expression.

• As we know that the subtraction is an arithmetic operation that represents the operation of removing objects from a collection.
• Subtraction is denoted by the minus(-) sign.
• By using the properties of subtraction, we are solving the above equation.

We are solving in the following way:

We have,

i) subtract $-50 \ from\ 30$

$=>30-(-50)\\=>30+50\\=>80$

and

ii) subtract $50 \ from\ -40$

$=>-40-50\\=>-90$

Hence, the solution of the above equation is:

$a)\ 80\\b)\ -90$
