Pi is actually one of the letters of the Greek alphabet, but it is most known in the math field as the ratio between the circumference of a circle and the circle's diameter.
There is no exact measure of pi, as it does not terminate but it starts like:
3.14159265
The like terms are 6 and 4:
6 + x + 4
= x + 10
