Absolute Value -How far a number is from zero.
Example "-6" is 6 away from zero, but "-6" is also 6 away from zero. So, the absolute value of 6 is 6, and the absolute value of -6 is also 6. The symbol "|" is placed either side to mean "Absolute Value", so we can write: |-6| = 6
Associative property- mathematical expression means that the order of the operations can be changed or regrouped so long as the operands (numbers or terms) are not changed.
Example addition: (6 + 3) + 4 = 6 + (3 + 4)
Because 9 + 4 = 6 + 7 = 13
Example multiplication: (2 × 4) × 3 = 2 × (4 × 3)
8 × 3 = 2 × 12 = 24
Closure Property - System of whole numbers is closed under addition, this means that the sum of any two whole numbers is always a whole number.
Example 1 = with the given whole numbers 4 and 9, Explain Closure Property for addition of whole numbers.
Answer= Find the sum of given whole numbers
4 + 9 = 13 as we know that 13 is also a whole number,
Commutative property- states that order does not matter. Multiplication and addition are commutative.
Example- 4 • 2 = 2 • 4, 4 + 2 = 2 + 4, 2 ≠ 2 – 4, 4 −4 ÷ 2 ≠ 2 ÷ 4
Composite Number - A whole number that can be divided evenly by numbers other than 1 or itself.
Example: 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is a composite number.
But 7 cannot be divided evenly (except by 1 and 7), so is NOT a composite number (it is a prime number).
Whole numbers above 1 are either composite or prime.
Decimal - Based on 10
Example: the numbers we use in everyday life are decimal numbers, because there are 10 of them (0, 1, 2,3,4,5,6,7,8 and 9).
Often "decimal number" is also used to mean a number that uses a decimal point followed by digits that show a value smaller than one.
Example: 45.6 (forty-five point six) is a decimal number.
Denominator -The bottom number in a fraction.
Shows how many equal parts the item is divided into.
Difference - The result of subtracting one number
