**Question 5.** **Asked on :**09 January 2019:09:37:10 AM

Ques.1. prove that 2+2= 5

*-Added by Master Purushottam* **Mathematics** » **Number System**

**Answer:**

Start with: -20 = -20

Which is the same as: 16-36 = 25-45Which can also be expressed as: (2+2) 2 (9 X (2+2) = 52) 9 X 5

Add 81/4 to both sides: (2+2) 2 (9 X (2+2) + 81/4 = 52) 9 X 5 + 81/4

Rearrange the terms: ({2+2}) 9/2) 2 = (5-9/2) 2

Ergo: 2+2 - 9/2 = 5

Hence: 2 + 2 = 5
