Question

Evaluate a + b for a = 2 and b = 3.
1
5
6
Which one is it ??

Answer 1

Answer: +5

Step-by-step explanation: In this problem we're going to evaluate a + b knowing that a = 2 and b = 3.

So the first thing we want to do is substitute these numbers into our problem.

Since a = 2, we're going to replace this a with a 2 and as we do that, we're going to put that 2 in parentheses.

Then we have + b which is 3 so we will replace the b with a 3. So we have (2) + (3) which simplifies to +5.

Answer 2

5

Explanation:

Let the two numbers be represented by variables a and b.

The value of variable a is given as 2.

The value of variable b is given as 3.

Sum of two variables a and b is represented as a+b.

In this case, substituting the given values of a and b in the expression,

a+b = 2+3 = 5

Hence the required value of the given expression is 5.

1 is not the correct option since the sum of two positive numbers must be greater than either number.

Similarly 6 is also incorrect.
