Divisibility Rules:
Divisible by:
2 - If the last digit is even, the number is divisible by 2.
3 - If the sum of the digits is divisible by 3, the number is also.
4 - If the last two digits form a number divisible by 4, the number is also.
5 - If the last digit is a 5 or a 0, the number is divisible by 5.
6 - If the number is divisible by both 3 and 2, the number is also divisible by 6.
7 - Take the last digit, double it, and subtract it from the rest of the number; if
the answer is divisible by 7 (including 0), then the number is also.
8 - If the last three digits form a number divisible by 8, then so is the whole
number.
9 - If the sum of the digits is divisible by 9, the number is also.
10 - If the number ends in 0, it is divisible by 10.

contained in another quantity.

2. Associative Property of Multiplication – you can group
factors differently. The product is always the same.
Example: (5 X 4) X 2 = (5 X ( 4 X 2))
20 X 2 = 5 X 8 = 40

Divide the sum by the number of elements in the data set –
7
4 28
7 is the mean.

2 W + 2L = P
2 X ( W + L) = P (Distributive Property of Multiplication)
Prime Number – a number that has only two factors, 1 and the
number itself.
Example: 2, 3, 5, 7, 11, 13, 17, 19 are prime numbers. For the
number 3, the only way to get the number as a product is
using the factors 1 and 3 (1 X 3 = 3).
Pattern – a set of characteristics that are displayed repeatedly.
Example: Continue the sequence 35, 40, 45, 50, ___, ___, …
First, find the difference for 3 sequential pairs of numbers –
40 – 35 = 5, 45 – 40 = 5, 50 – 45 = 5. the difference is 5;
therefore, you can continue the sequence by “adding” 5 to
the last number in the sequence – 50, 55 (50 + 5), 60 (55 +5).

Rounding Rules –
1. Decide which digit is to be rounded (use place value
position names).
2. If the digit to its right is less than 5, the digit being rounded
stays the same and all digits to the right change to 0’s.
3. If the digit to its right is 5 or more, the digit being rounded
is increased by 1 and all the digits to the right change to 0’s.
Example: 423 rounded to the nearest “ten” is 420.
289 rounded to the nearest “ten” is 290.

Volume – the measure of the space a solid figure occupies.
Example:
Computing volume - W x H x D;
volume is expressed in cubic units.

Zero Property of Multiplication – see section M,
under Multiplication.
Numbers – there are three ways to write a number.
-- Standard Form – a number that is written using the
numeral symbols.
Example: 1, 456, 729
-- Written Form – a number that is written using the words
that show how many (quantity) and place value.
Example: One million, four hundred fifty-six thousand, seven
hundred twenty-nine.
-- Expanded Form – a number that is written by separating
it into parts by place value and by using multiplication to
show the value of the digit.
Example: 1 x 1, 000,000 + 4 x 100,000 + 5 x 10,000
+ 6 x 1, 000 + 7 x 100 + 2 x 10 + 9 x 1.
Place Value – the system used to give meaning to
numbers written in a series.
Example: 9 0 1, 2 3 4, 5 6 7, 8 9 0

+ 1 x 1, 000, 000, 000 + 2 x 100, 000, 000
+ 3 x 10, 000, 000 + 4 x 1, 000, 000 + 5 x 100, 000
+ 6 x 10, 000 + 7 x 1, 000 + 8 x 100 + 9 x 10 + 0 x 1
Patterns
When finding the missing number in a list of numbers, you
need to figure out what pattern exists in the list. First, figure
out whether the numbers are increasing or decreasing. Then,
figure out how much more or how much less each number
is than the previous number.
Example: 10, 11, 12, ? , 1413 is the missing number.
Example: 40, 39, 38, ? , 3637 is the missing number.
Example: 4, 8, 12, 16, ? 20 is the missing number.
Patterns
When finding the missing picture in a list of pictures, you need
to figure out what pattern exists in the list. First, look at the
increasing or decreasing in the number of objects in each
picture in the list. Then, figure out how much bigger or how
much smaller each picture is than the previous picture.
Example: Complete the
geometric patterns.
Answer:
Answer:
Conversion
To change from one unit of measure to another unit of
measure
E.x., 12 inches = 1 foot
12 inches / 12 inches per foot = 1 foot
Formula
A set of symbols that expresses a mathematical rule.
E.x., Area = Length times Width
(A = L x W)
Decimal Place Value – the system used to give meaning to
decimal numbers written in a series.
Example: 0 . 2 3 4
0 .2 3 4
Tenths
Hundredths
Thousandths
