Let the number be 'm' & 'n' Hence mn = 88 m + n = 18 m = 18 - n Substitute (18 - n)n = 88 18n - n^2 = 88 n^2 - 18n + 88 = 0 This does not readily factor so apply the Quadratic Eq'n. n = { --18 +/-sqrt[(-18)^2- 4(1)(88)]} 2(1) n = { 18 +/- sqrt[324 -352]} / 2 n = { 18 +/-sqrt[-28]} / 2 This is unresolved as you cannot take the 'square root; of a negative number.
The answer is three. 6 x 3 = 18
6 times 18 equals 108.
18
it equals 18 times 18. 18 times 18 equals 324. 324 is your answer.
What times what equals 18
How about: 8*6*4 = 192
The answer to that question is 2 times a -4 equals -8
I
9.75 times 8 equals 78.
-18
6 times 5 equals 30. 30 times 8 equals 240.
