Answer to an addition problem
- Answer to a multiplication problem
- Ex. 3x5=15
Answer to a subtraction problem
Answer to a division problem
A number by which another number is to be divided
The number that is being divided
A number that can only have factors of 1 and itself
Ex. factors of 5 1,5
A number that has factors other than 1 and itself
Ex. factors of 6 1,2,3,6
Any number that ends in 1,3,5,7,9
Any number that ends in 0,2,4,6,8
Factors are numbers you can multiply together to get another number
Ex. Factors of 16 are 1,2,4,8,16
A number that can be divided by another number without a remainder
- Ex. First 5 multiples of 7 are
Greatest Common Factor (GCF)
- The highest number that divides exactly into two or more numbers
- Example: the GCF of 12 and 30 is 6, because 1, 2, 3 and 6 are factors of both 12 and 30, and 6 is the greatest.
Least Common Multiple (LCM)
The smallest number that is a multiple of two or more numbers. Example: the Least Common Multiple of 3 and 5 is 15
You get the same answer when you multiply a number by a group of numbers added together as when you do each multiplication separately Example: 3 × (2 + 4) = 3×2 + 3×4
To bring two or more numbers (or things) together to make a new total. Here 1 ball is added to 1 ball to make 2 balls
Taking one number away from another
Repeated addition. For example: 5 × 3 = 5 + 5 + 5 = 15
To divide is to split into equal parts or groups.
Ex. 8 divided by 2 = 4
When something is the same
Ex. 8/8 = 1
- More than one digit
- Ex. 36
When one number can be divided by another and the result is an exact whole number. Example: 15 is divisible by 3
The top number in a fraction, shows how many parts we have.
Ex. 7/8 7 is the numerator
- The bottom number in a fraction. Shows how many equal parts the item is divided into.
- example 3/4, 4 is the denominator
A mixed fraction is a whole number and a fraction combined into one "mixed" number. Example: 1½ (one and a half) is a mixed fraction
