Question

Evaluate a+(-b)a+(−b)a, plus, left parenthesis, minus, b, right parenthesis where a = 4a=4a, equals, 4 and b = 2b=2b, equals, 2.

Answer 1

The final answer is 2.

Step-by-step explanation:

Given expression,

$a+(-b)$

We need to find the value after evaluating.

Solution,

we have to solve for $a+(-b)$.

we have also given that;

$a=4$    and

$b=2$

Now we substitute the given values of 'a' and 'b'.

$4+(-2)$

Here we have to multiply the positive sign with negative sign.

And we know that product of positive sign and negative sign is negative sign.

So we get;

$4-2$

Now by applying subtraction property, we get;

$2$

Hence The final answer is 2.
