90/5 = 1818/2 = 9
7 + 90 / 9 + 10 + 42 - 7 7 + 10 + 10 + 16 - 7 36
90 minus 75 =15 therefore 15 + 75 = 90
108 remainder 3 :D
If 2.3 times t = 90.... 90 divided by 2.3 = 39.1 therefor t=39.1
22150.5
90/5 = 1818/2 = 9
(-11) x (-10) + (-20) 110 + (-20) 90
270
7 + 90 / 9 + 10 + 42 - 7 7 + 10 + 10 + 16 - 7 36
90
4 + 5 - 90 + 76 = -5
(-6) x (-3) = 18 (-10) x (-9) = 90 18 - 90 = -72
The question was cut up a bit. Some possibilities: 90 minus 2 [ 90 - 2 = 88 ] 90 plus 2 [ 90 + 2 = 92 ] 90 times 2 [ 90 * 2 = 180 ] 90 divided-by 2 [ 90 / 2 = 45 ] 90 to-the-power-of 2 [ 90^2 = 8,100 ] 90 equals 2 [ No Solution ] Add on to the discussion to edit the question, if it wasn't answered.
90 minus 75 =15 therefore 15 + 75 = 90
The answer of 17 + 123 is 140 and then minus 50 is 90
76 - 90 = -18 -18 - -48 = 30.
