Even and Odd Numbers

now? Multiples of a number are numbers which can be divided exactly by that number, leaving no remainder. A multiple of a number is the product of that number and any whole number. For example, the number ‘600’ is a multiple of ‘100’ 6 x 100 = 600. This can also be checked by dividing 600 ÷ 6 = 100.
