The basic calculations we make in everyday life: addition, subtraction, multiplication and division.
What is Arithmetic?
100
Subtract. Take away. Decrease by.
What is minus?
Example: 8 minus 3 is 5. 8 - 3 = 5
100
Counting forwards in multiples or intervals of a given number.
What is skip counting?
Count by 2's...2,4,6,8,10...
100
At the Count's castle, the number on the door.
What is the Lords?
100
Exactly the same amount or value.
What is equal?

200
To bring two or more numbers (or things) together to make a new total.
What is Add?
200
The result of subtracting one number from another. How much one number differs from another.
What is difference?
Example: The difference between 8 and 3 is 5.
200
The number that gets multiplied.
But because you can multiply the two numbers in any order, it is better to use the word "factor".
What is multiplicand.
Example: in 6 x 9 = 54, 9 is the multiplicand.
200
The number you divide by.
What is divisor?
dividend ÷ divisor = quotient
Example: in 12 ÷ 3 = 4, 3 is the divisor
200
Finding a value that is close enough to the right answer, usually with some thought or calculation involved.
What is estimation?
Example: Sam's estimation of 400 bricks to build the wall was very good, as there were only 12 bricks left over.
300
Any of the numbers that are added together.
What is Addend?
300
The number that always goes first or on top in a subtraction equation.
What is the largest number?
300
Items (such as objects, numbers, etc.) arranged in rows and columns.
What is array?
300
The amount that you want to divide up.
What is dividend?
dividend ÷ divisor = quotient
Example: in 12 ÷ 3 = 4, 12 is the dividend
300
This says that two things are the same, using mathematical symbols.
What is equation?
An equal sign (=) is used
Example: 7+2 = 10-1
400
This "law" says that you can swap numbers around and still get the same answer when you add.
Or when you multiply.
What is Communitive Law?
You can swap when you add: 6 + 3 = 3 + 6
400
To rearrange the formation of a group used to assist when trading or carrying in addition or subtraction.
What is regrouping?
400
Factors are the numbers you multiply together to get another number.
What is a factor?
Example: 3 and 4 are factors of 12, because 3x4=12.
400
The answer after you divide one number by another.
What is quotient?
dividend ÷ divisor = quotient
Example: in 12 ÷ 3 = 4, 4 is the quotient
400
A mathematical process.
What is an operation?
The most common are add, subtract, multiply and divide (+, -, ×, ÷ ).
If it isn't a number it is probably an operation.
Example: In 25 + 6 = 9, the operation is add
500
The result of adding two or more numbers.
What is sum?
Example: 9 is the sum of 2, 4 and 3, because 2 + 4 + 3 = 9.
500
This "Law" says that you can swap numbers around and still get the same answer when you multiply.
Or when you add.
What is Communitive Law/Property
You can swap when you multiply: 2 × 4 = 4 × 2
500
The answer when two or more numbers are multiplied together.
What is product?
500
When one number can be divided by another and the result is an exact whole number.
What is divisible?
Example: 15 is divisible by 3, because 15 ÷ 3 = 5 exactly
But 9 is not divisible by 2 because 9 ÷ 2 is 4 with 1 left over.
500
A symbol used to make numerals.
What is digit?
0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 are the ten digits we use in everyday numbers.
