Question

What is 2+2 in mathematics

Answer 1

4

Explanation:

2+2 is 4 because if you have 2 fingers you just add 2 more and when you look at your hand you'll be raising up only 4 fingers.

Answer 2

Let's start with

16-36 = 25-45

If we add 81/4 in both sides

16 - 36 + (81/4) = 25 - 45+ (81/4)

Simplyfing

(4 - (9/2))² = (5 - (9/2))²

Take the square root

4 - (9/2) = 5 - (9/2)

Add 9/2 in both sides

4 - (9/2) + (9/2) = 5 - (9/2) + (9/2)

4 = 5

As we know 2.2 = 4

2.2 = 5

And 2.2 is equal to 2 + 2

2 + 2 = 5
