Question

Subtract: $-72from-34$

Answer 1

Subtraction of integers

We have to subtract $-72from-34$

Or we can say $-34-(-72)$

$=-34+72\left\{\left(-\right)\left(-\right)+\left(+\right)\right\}$

$=38$

( We know that to add a negative and a positive integer we just find the difference of their absolute value (leave the sign) and assign the sign of the addend having a greater absolute value )

Hence, $-34-(-72)=38$.
