## The area of the auditorium.

### This is the carpet/rug.

Formula

13.6m x 10.7m 145.52.

13.6m

10.7m

The area is 145.52

## Perimeter

### This rectangle has an area of 2 by 5. It’s perimeter is 14 square blocks

This is a percentage. A percentage is a number over 100. The slanted line in% is a one and the two circles next to the slanted line. So % stands for 100.

100

## Math Problems

The ball is dropped from a 128 feet building. Each time it bounces it bounces half-way up than the last time. How far will the ball bounce up when it bounces on the fourth time? Here is the answer.

128 ft.

Frog Problem: A frog fell into a 10- foot well. He has to climb out because he cannot hop out. Every day, he climbs 3 feet and every night, he slides back 2 feet. At this rate, how many days will it take poor Froggie to climb out?

## Factors

### Factors are numbers divisible by a number.

Ex. The factors of 27 are 9,3 and 1,27.

Ex. The factors of 21 are 7,3 and 1,21.

### Prime numbers are numbers that are only divisible by the number itself and 1.

These are also prime numbers:

2, 3, 5, 7, 11, 13, 17, 19, 23, 26 and so on.

2,1 and 3,1 and 5,1 and 7,1 and 11,1 and 13,1 17,1 19, 23, 26 and so on.

Factors :

### Composite numbers are the opposite.

Like 10, 20, 30, 27, 12, 15, and so on.

### Patterns of 11

• 112 = 121

• 1112 = 12321

• 11112 = 1234321

• 111112 = 123454321

• 1111112 = 12345654321

• 11111112 = 1234567654321

• 111111112 = 123456787654321

• 1111111112 = 12345678987654321

• 11111111112 = 1234567900987654321

## Glossary of Math

### Century

• A century is another way to express a hundred years

A 100 years = a century!

A century is the same as a hundred years!

### Congruent

• Two things that are same (Ex. Same size, same shape).

## Combining Like Terms

Example: 12z +17z = ?

It is like this:12 soccer balls + 17 soccer balls = 29 soccer balls.

## Real Algebra

One number is ten times another. Their sum is 55. Find the numbers.

First do this.

1. Y + 10Y = 55
