Find the 2 numbers that bond together to make a tidy number (multiple of 10) then add on the remaining number.
e.g. 6 + 7 + 4 = ? (6 + 4) = 10 10 + 7 = 17 | 77 + 5 + 3 = 77 + 3 = 80 80 + 5 = 85 |
5 + 2 + 8 = 10+5=15 | 55 + 4 + 5 = 60+4=64 |
13 + 5 + 7 = 20+5=25 | 7 + 2 + 38 = 40+7=47 |
8 + 5 + 12 = 20+5=25 | 4 + 8 + 26 = 30+8=38 |
15 + 5 + 6 = 20+6=26 | 6 + 64 + 3 = 70+3=73 |
7 + 17 + 3 = 20+7=27 | 9 + 3 + 61 = 70+3=73 |
19 + 5 + 1 = 20+5=25 | 28 + 2 + 6 = 30+6=36 |
5 + 7 + 13 = 20+5=25 | 9 + 101 + 8 = 110+8=118 |
16 + 4 + 2 = 20+2=22 | 145 + 8 + 5 = 150+8=158 |
