w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
w=x-y w+y=x
They are identities because they are true for ALL values of w and x.
w x 1
w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
if x + y = w, then x = w - y
w=x-y w+y=x
They are identities because they are true for ALL values of w and x.
2 x 2 x 7 x w x w x w
Xx x x
It is 2w.
x - y = w Add y to both sides: x = w + y
It is 2w.
There is no difference between L x W and W x L For example if L = 5 and W = 3 L x W -> 5 x 3 = 15 W x L -> 3 x 5 = 15
b has x + W.
