Question

. Mahesh worked in a firm for a certain number of years which equals

Answer 1

The sum of numbers or expression involves adding the expressions and the numbers together.

Assume that the sum of the degrees is given as:

$Sum = 3 + 4 - 2 + 1$

The above sum can be rewritten as:

$Sum = 3 + 4 +(- 2) + 1$

Take the sum of all the numbers (including -2 in bracket)

$Sum = 6$

If the sum of the degrees is given as $Sum = 3 + 4 - 2 + 1$, then the number of years he worked would be 6
