1) 6 (14 x 6 = 84)
2) 1 (23 x 1 = 23)
3) 7 (-6 x 7 = 42)
4) -1, -5, 2 (-1 x -5 = 5 and 5 x 2 = 10)
5) -116393 (487 x -239 = -116393)
6) -7.5 (7 + 8 = 15 and 15 ÷ -2 = -7.5)
7) -4 (8² = 64 , -4 x 4 = -16 and 64 ÷ -16 = 4)
8) -1 (12 x 12 = 144 so - 144 then you do 12² = 144 and finally -144 ÷ 144 = -1)
9) -2 (-8 ÷ 4 = -2)
10) 2 (16 - 8 = 8 , 2 x 2 = 4 and 8 ÷ 4 = 2)
I hope this helps
