It's a tricky one, but it has a solution.
Please show your work.

Answer 1

Assuming that your looking for a pattern this is what I was able to find...

2*3= 6+(2*1)=8

3*7= 21+(3*2)=27

4*5= 20+(4*3)=32

5*8= 40+(5*4)=60

6*7= 42+(6*5)=72

7*8= 56+(7*6)=98

Answer 2

Formula: a + b = c × a - a

2+3 = 5
5 × 2 = 10
10 - 2 = 8

3 + 7 = 10
10 × 3 = 30
30 - 3 = 27

4 + 5 = 9
9 × 4 = 36
36 - 4 = 32

5 + 8 = 13
13 × 5 = 65
65 - 5 = 60

6 + 7 = 13
13 × 6 = 78
78 - 6 = 72

7 + 8 = 15
15 × 7 = 105
105 - 7 = 98

Answer: 7 + 8 = 98
