Addition problems use the plus sign + (for adding) and subtraction problems use the minus sign - (for taking away) when they are written down. The plus sign denotes that one or more numbers should be added to others to get a larger amount, for example 5 + 5 = 10. The minus sign means that one or more numbers should be taken away, for example 8 - 4 = 4. There are several techniques that we can use to simplify math problems and make them easier, such as counting in steps, rounding numbers up or down, or using number bonds.

1 .
Which of these pairs would not total 700?
673 + 37
654 + 46
687 + 13
648 + 52
673 + 37 = 710
2 .
Which is the best method of calculating the missing number in this problem: ___ - 23 = 176?
176 - 23
176 + 23
23 - 176
123 - 76
176 + 23 = 199
so 199 - 23 = 176
3 .
What is the best method of subtracting 79?
Add 80 subtract 1
Add 80 add 1
Subtract 80 subtract 1
Subtract 80 add 1
e.g. 456 - 79 so 456 - 80 = 376 + 1 = 377
4 .
How would you calculate 3,004 - 2,898?
Double 3,000 then adjust
Count in 1s from 2,898 to 3,004
Count up in 3 steps from 2,898 to 3,004
Count up in 5 steps from 2,898 to 3,004
e.g. 2,898 + 2 = 2,900 + 100 = 3,000 + 4 = 3,004 so 3 steps gives the answer 106
5 .
Which is the best method of calculating 1.5 + 1.6?
Double 1.5 add 0.1
Double 1.5 add 1
Double 1.5 subtract 1
Double 1.5 subtract 0.1
1.5 x 2 = 3.0
3.0 + 0.1 = 3.1
so 1.5 + 1.6 = 3.1
6 .
What would you add to 6.4 to make 7?
0.4
0.6
0.7
1.6
The best way to work this out is to take 6.4 from 7, which would give you the answer 0.6
7 .
Which strategy would be best to calculate 347 + 97?
Add 100 to 347 subtract 3
Add 100 to 347 add 3
Subtract 100 from 347 add 3
Subtract 100 from 347 subtract 3
347 + 100 = 447
447 - 3 = 444
so 347 + 97 = 444
8 .
Which of these pairs does not total 100?
28 + 72
39 + 61
17 + 83
57 + 53
57 + 53 = 110
9 .
Which of these pairs does not total 1?
0.2 + 0.8
0.4 + 0.6
0.7 + 0.3
0.1 + 0.8
1 + 8 = 9
so 0.1 + 0.8 = 0.9
10 .
Which number sentence is incorrect?
875 - 56 = 819
819 + 56 = 875
