first add the two numbers:2+3=5
and then subtract 1:5-1=4
then multiply the result with with the first digit given:4*2=8
and for it is true and hence the answer is given as follows 7+8=?
7+8=15
15-1=14
14*7=98

7+8=56+42=98
because
7*8=56
7*6=42
so
56+42=98

If 2+3=8, (2*3=6+2*1=6+2=8)
3+7=27, (3*7=21+3*2= 21+6=27)
4+5=32, (4*5=20+4*3=20+12=32)
5+8=60, (5*8=40+5*4=40+20=60)
6+7=72, (6*7=42+6*5=42+30=72)
then 7+8=?? (7*8=56+7*6=56+42=98)
