*Expressions and Formula*

L.O To be able to collect like terms, simplify expressions and write expressions

When expressing events using algebra the **multiplication sign disappears** for

**Example 1:**

There are 4 rows of students and each row has the same number of students.

We will use the letter **‘n’** to stand for the **number of students** in a row

So, in 4 rows there will be **4 X n** students

This is written as **4n**.

6 students then come along to sit on the row, so now the total number of students altogether is: **4n + 6**

**Writing Expressions**

**Example 1:**

a) There are b large nails in a box and p small nails in each packet. Samantha buys 5 boxes of large screws. Write an expression for this.

b) Samantha also buys 2 packets of small nails. She uses 7 large nails and 5 small nails. Write down an expression in terms of b and p for the total number of large screws and nails left.

So in total Samantha has **5b + 2p** nails altogether. **5b + 2p** – 12 is your final answer.
