For example:

Is the 2560 divisible by 10?

Yes! because it ends with 0 (zero).

Is the 5648 divisible by 10?

No! because it ends with 8 and its suppose to be 0. So its not divisible by 10.

### what's a numerator?

### number of the day number 7 and 15

if your diameter is 6 then plug in 3.14 x 6. this will equal 18.84.

following the first example with the diameter being 6, you can calculate the radius and use that as well. the radius equals 1/2 of the diameter so radius equals 6 divided by 2. that equals 3. now you can plug 3 into the formula 2(3.14) x 3 which also equals 18.84.

### What are the different types of estimating???

Under Estimate-the estimate that you are sure is less than the actual answer.

Over Estimate-the estimate that you are sure is larger than the actual answer.

Front-end Estimation-is always under estimating, use the greatest place value the numbers have in common.

### what are variables ?

Variables are used throughout Algebra, Geometry, and Calculus. They are the basic building blocks. Variables are therefore very important to understand.

A variable is a symbol, such as x, that is used to describe an unknown number. In functions variables often represent not one number, but many different numbers. Understanding variables is essential for you to understanding problems that will need to be graphed.

### bedmas

In order to solve a question with multiple operations (add/subtract, multiply/divide) there is an order to follow often referred to as 'BEDMAS'

BEDMAS is an acronym that stands for;

B-brackets

E-exponents

DM-multiply or divide (left to right)

AS-add subtract (left to right)

this is to help students remember what order to do the work in.

Here is a similar question,

(3 + 6) - 8 × 3 / 24 + 5

Following BEDMAS, we need to start with B-brackets,

(3 + 6) - 8 × 3 / 24 + 5

= 9 - 8 × 3 / 24 + 5

Then E-exponents, none, followed by DM-divide multiply (left to right),

= 9 - 8 × 3 / 24 + 5 (multiply)

= 9 - 24/24 + 5 (divide)

= 9 - 1 +5

And finish with AS-add subtract,

= 9 - 1 +5

= 8 +5

= 13

### Number of the day number 3

3. Write the number of the day in written form.

### How to add Mixed Numbers

What is a mixed number? - a mixed number is a number made up of a whole number and a fraction.

E.g. 1 1/2, 2 3/2 <-- WRONG!!

Instructions:

1. Deal with the fractions first. If they have a common denominator, go ahead. But if they have a different denominator, find a common denominator.

2. Then deal with the whole numbers.

3. Finally, combine the fractions and the whole denominators.

4. And if you can, bring the fraction to its lowest terms

Here's a little test for you:

1 1/2 + 3 3/4 = ?

### DENOMINATOR AND NUMERATOR

Denominator is the bottom number of a fraction and tell us how many equal parts the whole is divided into.

example:

3/ 4

4 is the denominator.

Numerator is the top number of a fraction and tell us how many parts of the whole we have or dealing with.

example:

5/ 6

5 is the numerator.
