5f + 60 = 90
90 - 60 = 30
5 * ? = 30
5 * 6 = 30
(5)6 + 60 = 90
90 + 90 + 60 = 240
390
30 + 5f = 120 -30 -30 5f = 90 /5 /5 f = 18 Check: 30 + 5 (18) = 120 30 + 90 = 120 120 = 120
The result of the equation - 90 plus 90 plus 60 plus 80, is found as follows; 90 + 90 + 60 + 80 = ( 90 + 90 ) + 60 + 80 = 180 + ( 60 + 80 ) = 180 + 140 = 320 Answer = 320
The result of the equation - 60 plus 90 plus 60 plus 80, is found as follows; 60 + 90 + 60 + 80 = ( 60 + 90 ) + 60 + 80 = 150 + ( 60 + 80 ) = 150 + 140 = 290 Answer = 290
90 + 60 = 150
60 multiplied by 90 is 5,400.
It is: 80+90+60 = 230
The result of the equation - 110 plus 90 plus 60 plus 80, is found as follows; 110 + 90 + 60 + 80 = ( 110 + 90 ) + 60 + 80 = 200 + ( 60 + 80 ) = 200 + 140 = 340 Answer = 340
The result of the equation - 30 plus 90 plus 60 plus 80, is found as follows; 30 + 90 + 60 + 80 = ( 30 + 90 ) + 60 + 80 = 120 + ( 60 + 80 ) = 120 + 140 = 260 Answer = 260
The result of the equation - 20 plus 90 plus 60 plus 80, is found as follows; 20 + 90 + 60 + 80 = ( 20 + 90 ) + 60 + 80 = 110 + ( 60 + 80 ) = 110 + 140 = 250 Answer = 250
The result of the equation - 10 plus 90 plus 60 plus 80, is found as follows; 10 + 90 + 60 + 80 = ( 10 + 90 ) + 60 + 80 = 100 + ( 60 + 80 ) = 100 + 140 = 240 Answer = 240
