X * A= Y * A

then X = Y

for example

2 * 0 = 3 * 0 so 2 = 3

Any number to the 0 power equals 1

0 to any power equals 0

1 = 0 to the zero power = 0

So 1 = 0

multiply both sides by ( X - Y )

X - Y = 0

Add Y

X = Y

If A * B = C then C / B = A

0 * B = 0

0 / 0 = B

for example

0 / 1 = 0 so 0 / 0 = 1

0 / 5 = 0 so 0 / 0 = 5

1 = 0 / 0 = 5

so every number equals every other number

Real life example

If $1 equals 0 grams of gold

Then $1 = 0 grams of gold = $2
