Inequalities, Multiples and Factors Help

ROUNDING TO THE NEAREST 10

When you are rounding a number to the nearest 10, it is the ones digit that you need to look at.

  • If the ones digit is less than 5, the number is rounded down to the previous ten;
  • If the ones digit is 5 or more, the numbers is rounded up to the next ten.

Examples

136 is rounded up to 140 because the ones digit is a 6.

394 is rounded down to 390 because the ones digit is a 4.

220 stays the same value because it is already a multiple of 10.

ROUNDING TO THE NEAREST 100

When you are rounding a number to the nearest 100, it is the tens digit that you need to look at.

  • If the tens digit is less than 5, the number is rounded down to the previous hundred;
  • If the tens digit is 5 or more, the numbers is rounded up to the next hundred.

Examples

354 is rounded up to 400 because the tens digit is a 5.

1629 is rounded down to 1600 because the tens digit is a 2.

1300 stays the same value because it is already a multiple of 100.

ROUNDING TO THE NEAREST 1000

When you are rounding a number to the nearest 1000, it is the hundreds digit that you need to look at.

  • If the hundreds digit is less than 5, the number is rounded down to the previous thousand;
  • If the hundreds digit is 5 or more, the numbers is rounded up to the next thousand.

Examples

7603 is rounded up to 8000 because the hundreds digit is a 6.

4396 is rounded down to 4000 because the hundreds digit is a 3.

12000 stays the same value because it is already a multiple of 1000.

INEQUALITIES

There are two main symbols used to express an inequality:

  • > the greater than symbol;
  • < the less than symbol.

One way to remember the symbol is to think of it as a greedy mouth. The mouth will always try to eat the biggest number.

Examples

54 > 39

17 < 25

MULTIPLES

If a number is a multiple of another number, it means that it can be made out of adding groups of the other number together.

Examples

12 is a multiple of 4 because 4 + 4 + 4 = 12 (or 4 x 3 = 12)

27 is a multiple of 9 because 9 + 9 + 9 = 27 (or 9 x 3 = 27)

17 is not a multiple of 4 because it cannot be made by adding groups of 4 together.
