-1
-7
The numbers are 4 and 13
4 x 13 = 52
they multiply to a product
-28
How about: 4*5*7 = 140
-13
9 + 28 +37 + 6 + 15 + 4 = 99
9+8+7+65+4+3+2+1=99
No you don't multiply the 4 numbers you take radius times radius
List numbers that multiply to make 28 and find their sums. Since negative times a negative is positive, list the negatives. -1, -28 = -29 -2, -14 = -15 -4, -7 = -11 Aha! -4 and -7 multiply to make 28 and add to -11; therefore, -4 and -7 are the two numbers.
