This is a fun little math exercise to demonstrate that in modern math 2 + 2 doesn’t always equal 4. I have found that it can amaze and confuse your mother, grade school kids, and math-impaired siblings. This works especially well on a computer spreadsheet where you can format the cells and change the numbers right before their eyes.
1.6 + 1.6 = 3.2
1.9 + 1.9 = 3.8
2.4 + 2.4 = 4.8
Round the numbers in those equations to the nearest whole number and you get 3 different answers to 2 + 2:
2 + 2 = 3
2 + 2 = 4
2 + 2 = 5
