pls I need help with my math homework
math
2 plus 2 = 2x2 = 2/1 + 2/1 equals 2/1 x 2/1 equals (2-1)(2-1) equals 1x1 equals 1 mathematically true statement
2 + 2 = 2 + 1 + 1
Turn the + sideways to make x. Thus you turn the ones sideways as well to make: 2 + - + - .
Since there’s minus nothing, we can put one next to them, as a placeholder. So we have 2 + -(1) + -(1). So, we get 2-2, which is O. We know this makes sense because at the start of this problem we turned some things on their sides. So, to finish this we have to turn O on its side. We get O still. So, 2+2=O
From this we see even more things, like + seemingly equalling -, but that’s a lesson for another day.
whats 2+2
