The sum of the sum of x and z and the difference of y and z
Take this algebraic expression in 3 parts:
Step 1: The sum of x and z is written as:
x + z
Step 2: The difference of y and z is written as:
y - z
Step 3: the sum of the sum and difference is written as:
x + z + (y - z)
x + z + y - z
Cancelling the z terms, we get:
x + y
