Follow up day 3

Day 3 WALT: I am learning to use compatible numbers to solve problems like 5 + 3 + 6 - 8, by first adding five and three to get eight then removing the eight.

  1. 4 + 2 + 5 - 9 =   4+2=6  6+5=11 11-9=2
  2. 8 + 5 + 2 -7 =    5+2=7   7+8=15  15-7=8
  3. 10 + 2 + 7 - 12 =  7+2=9  9+10 =19  19-12=7
  4. 10 + 5 - 15 =     10+5=15  15-15=0
  5. 2 + 6 + 4 + 3 - 7 =    6+4=10  4+2=6  10+6=16   16-7=9
