Firstly what is sum and product in maths

They are terms used in maths, another way of saying total

The term for the total in

+ Addition======Sum

x Multiplication===Product

- Subtraction====Difference

/ Division====== Quotient

(sorry about the computer sign for division, when will manufacturers sort it)

The answer = 9, 16, 21, 24, 25

why? well

Pairs of numbers with the sum of 10 are:-

1+9=10

2+8=10

3+7=10

4+6=10

5+5=10

so that means therefore

1x9=9

2x8=16

3x7=21

4x6=24

5x5=25

So the products or totals of these pairs of numbers are

9,16,21,24 and 25

Dont forget you can also reverse the sums as well, but it won't change my answer.

What I mean is, mirror the sums (I am sure you know this but)

1+9 is the same as 9+1 and so on

as is

1x9 is the same as 9x1 and so on

Do you see this (I am sure you did) but for our younger viewers I thought it was worth mentioning

Good luck with your Year 5 Maths everyone
