**a = 1**

b = 1

b = 1

This gives us:

**a = b**

Now multiply both sides by

*a*:

**aa = ab**

**a^2 = ab**

Subtract both sides by

*b^2*:

**a^2 - b^2 = ab - b^2**

The conjugate rule now gives us:

**(a + b)(a - b) = ab - b^2**

Extract

*b*on the right side:

**(a + b)(a - b) = b(a - b)**

Divide both sides by

*(a - b)*:

**a + b = b**

or in other words:

**1 + 1 = 1**
