x + 50 = 2x + 100 50 = 2x+100-x 50 = x + 100 50-100=x -50=x -50+50=0 -100+100=0 it is zero

If you are solving for x, x2 - 2x + 1 = 0 Factor: (x-1)(x-1) = 0 Therefore: (x - 1)2 = 0 (x - 1) = 0 x = 1

That is the Identity property (Additive Identity, in this case). x + 0 = x = 0 + x Any number added to zero results in the original number. There is a Multiplicative Identity (for multiplication, as you may have guessed) that used the number 1. x * 1 = x = 1 * x Any number multiplied by one results in the original number.
It is a consequence of the property that 0 is the additive identity.
It's called the zero property
Identity
The zero property because it has a zero.
zero property
The existence of an additive identity, denoted by 0, which has the property that x + 0 = 0 + x = x for all x belonging to a set of numbers.
83*0 = 0 is the multiplicative property of zero. Incidentally, the identity property of multiplication states that x*1 = x = 1*x for all x in the group. That is a different property though sometimes confused with this one.
x + 50 = 2x + 100 50 = 2x+100-x 50 = x + 100 50-100=x -50=x -50+50=0 -100+100=0 it is zero
Yes it does equal 0. This is proved by commutative property of maths which says that 2 numbers can be multiplied in many ways.
because its zero
It is called the zero property which says that any number into zero gives zero.
0 By the multiplication property of 0, any number multiplied by 0 equals 0
