the sum for 20 + 40 + 70 + 80 = 210
The sum answer = 3440
The answer = 3450
80 or 10 x 6 = 60 + 20 = 80 or(10*6)+20=80
The result of the equation - 130 plus 80 plus 20 plus 80, is found as follows;130 + 80 + 20 + 80= ( 130 + 80 ) + 20 + 80= 210 + ( 20 + 80 )= 210 + 100= 310Answer = 310
The sum of 75 plus 5 is 80.
42 (half of 80 is 40 and 10% of 20 is 2, therefore 40 + 2)
The answer = 3510
The result of the equation - 130 plus 80 plus 10 plus 80, is found as follows;130 + 80 + 10 + 80= ( 130 + 80 ) + 10 + 80= 210 + ( 10 + 80 )= 210 + 90= 300Answer = 300
Not with those numbers
The result of the equation - 130 plus 80 plus 60 plus 20, is found as follows;130 + 80 + 60 + 20= ( 130 + 80 ) + 60 + 20= 210 + ( 60 + 20 )= 210 + 80= 290Answer = 290
the sum of 67 + 13 = 80
