1 100 + 50 + 90 + 45 _____ 285
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
90
The answer of 17 + 123 is 140 and then minus 50 is 90
The answer = 3490
65 + 65 + 65 + 90 + 90 + 90 + 90 + 50 + 50 + 50 + 50 + 50 + 50 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 995
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

140
100 + 100, 50+50+50+50, or 120+ 90
The answer of 17 + 123 is 140 and then minus 50 is 90
The answer = 3490
-90 (when you add a negative you simply subtract so -40-50 is -90)
