50% is one-half, half of 90 is 45 so your answer is 135.
The equal sign is the same as the enter button
If all 4 sides are equal and the angles are not 90 degrees it is a rhombus.
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.

65 + 65 + 65 + 90 + 90 + 90 + 90 + 50 + 50 + 50 + 50 + 50 + 50 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 995
50 + 50 + 50 + 90 = 240
50 plus 50 plus 50 equal 150
The result of the equation - 50 plus 90 plus 60 plus 80, is found as follows; 50 + 90 + 60 + 80 = ( 50 + 90 ) + 60 + 80 = 140 + ( 60 + 80 ) = 140 + 140 = 280 Answer = 280
1 100 + 50 + 90 + 45 _____ 285
140
The sum of the equation - 990 + 880 +90 +790 +690 + 50, is found as follows;990 + 880 +90 +790 +690 + 50= (990 + 880) + (90 +790) + (690 + 50)= ( 1870 ) + (880 ) + ( 740 )= 3490Answer = 3490
8100 plus 90 plus 72 is equal to 8,262.
32+90+16=138
It is: 80+90+60 = 230
90
70 + 70 + 50 + 50 = 240
