Long Division with Remainders

When we are given a long division to do it will not always work out to a whole number.
Sometimes there will be numbers left over. These are known as remainders.
Taking an example similar to that on the Long Division page it becomes more clear:

435 ÷ 25

(If you feel happy with the process on the Long Division page you can skip the first bit.)

	4 ÷ 25 = 0 remainder 4	The first number of the dividend is divided by the divisor.
		The whole number result is placed at the top. Any remainders are ignored at this point.
	25 × 0 = 0	The answer from the first operation is multiplied by the divisor. The result is placed under the number divided into.
	4 – 0 = 4	Now we take away the bottom number from the top number.
		Bring down the next number of the dividend.
	43 ÷ 25 = 1 remainder 18	Divide this number by the divisor.
		The whole number result is placed at the top. Any remainders are ignored at this point.
	25 × 1 = 25	The answer from the above operation is multiplied by the divisor. The result is placed under the last number divided into.
	43 – 25 = 18	Now we take away the bottom number from the top number.
		Bring down the next number of the dividend.
	185 ÷ 25 = 7 remainder 10	Divide this number by the divisor.
		The whole number result is placed at the top. Any remainders are ignored at this point.
	25 × 7 = 175	The answer from the above operation is multiplied by the divisor. The result is placed under the number divided into.
	185 – 175 = 10	Now we take away the bottom number from the top number.
		There is still 10 left over but no more numbers to bring down.
		With a long division with remainders the answer is expressed as 17 remainder 10 as shown in the diagram Answer: 435 ÷ 25 = 17 R 10

Multiplication

What is Multiplication?

Multiplication is a process that we use to find the result when we multiply numbers together, for example: 12 times 33 equals 396

In mathematics we usually use symbols instead of words though, for multiplication sums you need to know that:

the symbol for times is ×         and        the symbol for equals is  =

so the above sum would change to be: 12 ×  33 = 396

 

On paper it is easier to solve these sums if you write them out in a different way:

  

    12
 × 33
---------
    36
+ 360
---------
   396

What is Subtraction?

Subtraction is a process that we use to find the result of taking numbers away from each other, for example: 45 minus 12 equals 33

In mathematics we usually use symbols instead of words though, for subtraction sums you need to know that:

the symbol for minus is -       and          the symbol for equals is =

 

so the above sum would change to be: 33 - 12 = 45

 

On paper it is easier to solve these sums if you write them out in a different way:

  45
- 12
--------
  33

Addition is a process that we use to find the result of adding numbers together, for example:   12 plus 33 equals 45

In mathematics we usually use symbols instead of words though, for additon sums you need to know that:

the symbol for plus is  +                 and               the symbol for equals is   =

so the above sum would change to be:   12+33=45

 

On paper it is easier to solve these sums if you write them out in a different way:
