Question

Find the value of : $35 - (20)$

Answer 1

Hint: Here, we have to subtract one two-digit number from another two-digit number. Given that the smaller number has to be subtracted from the bigger number. Do it carefully by perfect count.

Complete step-by-step answer:
We have to subtract from
Therefore-
$35 - (20) = 15$
Since, the smaller positive number is subtracted from the positive bigger number answer is positive number.

Additional information:
There are few concepts one has to follow while simplification of numbers.
For example:
$( - 3) + ( - 7) = ( - 10)$ if both the terms are negative with plus sign in between then do addition and give minus sign to the resultant answer.
$( - 3) + (7) = (4)$ if one term is negative and other positive with plus sign in between then do subtraction and give sign of the bigger number to the resultant answer. As a minus plus minus sign of a bigger number.

Note: Always know the basic concepts of addition and subtraction in mathematics and apply accordingly.
