Formula: _7 x 6_
171+3420
Answer: 3591

I have to figure out the missing numbers in this product formula. >.<
I'm so STUCK!!

I don't understand the question. How do the _7 x 6_ relate to the 171 + 3420??

Is it _7 x 6_ + 171 + 3420 = 3691???

Looks like the hints here are
171 + 3420
171 = 3*57; 3420 = 60*57
so
171 + 3420 = (60 + 3)*57 = 63*57 = 57*63

and

3591 = 3600 - 9
= 60^2 - 3^2
= (60 - 3)*(60 + 3)
= 57*63

LET THE DIGITS BE X7 x 6y = 3591

7y should end in 1

y = 3

X7 x 63 = 3591

X7 = 3591/63 = 57


X = 5

ANSWER 57 X63

57x63
