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
The sum of the equation - 990 + 880+40 +90 +790 +690, is found as follows;990 + 880 +40 +90 +790 +690= (990 + 880) + (40 +90) + (790 + 690)= ( 1870 ) + ( 130 ) + ( 1480 )= 3480Answer = 3480
The answer = 3490
The answer = 3510
90 + 900 = 990
The sum of the equation - 990 + 880 +90 +790 +690 + 20, is found as follows;990 + 880 +90 +790 +690 + 20= (990 + 880) + (90 +790) + (690 + 20)= ( 1870 ) + (880 ) + ( 710 )= 3460Answer = 3460
The sum of the equation - 990 + 880 +90 +790 +690 + 40, is found as follows;990 + 880 +90 +790 +690 + 40= (990 + 880) + (90 +790) + (690 + 40)= ( 1870 ) + (880 ) + ( 730 )= 3480Answer = 3480
