What is 2+2 in mathematics
2 answers:
Answer:
4
Step-by-step 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.
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
