# Week 8 — Math 10

This week, we began to learn chapter5–Polynomial. I think there are lots of fun to solve the problems of polynomial.

I felt so confused about lots of new words. But now I got those words.

**Variable: **the letter in a polynomial.

**Polynomial: (Note)**The exponent of any variable must be a positive integer.

**Degree: **The degree of a polynomial is the degree of the term with highest degree.

The **leading coefficient **of a polynomial in a single variable is the coefficient of the term with highest power of the variable.

**Zero pair: **a pair of terms that combined simplify yo zero.

**Distribute:** Multiplying a sum or difference by a common number. Used to remove brackets from an expression.

In this week, I also learnt how to use **Area Diagram, **this really helpful when I am doing those questions.
