In maths this recently p6\/7 have been learning many different ways to help you add and subtract. These are some ways help you get your maths right. One way is to work backwards,\u00a0 this is were if you have an adding sum and you want to check it is correct, you would subtract the second number from the sum from the answer and if it equals the first number of the sum, it is correct. Example: 42+56=98 to check: 98-56=42. Another technique is partitioning, which is when you split the sum into tens and units to make it easier. example: 97-34=63\u00a0 how to do it with partitioning: 90-30=60, 7-4=3, answer =60+3=63. p6\/7\u00a0 have learned many\u00a0 different techniques as well as these.<\/p>\n
