Question

What should be subtracted from $-23$ to get $-56$?

Answer 1

Let the required number be $x$

i.e., $x$ should be subtracted from $-23$ to get $-56$.

$\Rightarrow$ $-23-x=-56$

$\Rightarrow -x=-56+23$

$\Rightarrow -x=-33$

$\Rightarrow x=33$

Hence, $33$ should be subtracted from $-23$ to get $-56$.

Alternate method:

To get required number, Subtract $-56$ from $-23$.

$\Rightarrow -23-(-56)$

$=-23+56$

$=33$
