Answer:
9+8=17 | 2×17=34 | 29+33=62 | 164÷2=82| 20÷2=10 | 6×3=18 | 39-20=19 | 54+37= 91|
Step-by-step explanation:
9+8 is 17 since 9+9 is 18 so you just remove a number to make it 17 which is the same thing that happened to the nine that turned into an 8.
17×2 is 34 b/c 17+17 is 34. details to follow.
