Applying the laws of BODMAS, 1000 - (987/72) + 3 = 989.2916 recurring (that is, 989.2916666...)
No u idiot it is 1002

No: -987-987=-1974 However, 987-987=0, -987+987=0
789 x 789 = 622521.
-987 + 654 + 321 = 0 .

Zero out the Y to find X 3X - 2(0) = -789 3X = -789 X = -263 ------------- now to check you need to find Y, so zero out X 3(0) - 2Y = -789 - 2Y = - 789 Y = 394.5 0r 394 and 1/2 convert to fraction = 789/2 ------------ check 3(-263) - 2(789/2) = -789 -789 - 2(789/2) = -789 cancel one 2 and multiply through by that 2 -1578 + 789 = - 789 -789 = - 789 checks
987 is rounded to 990
