70 80 80 80 90 90 100 100 110 110 120 130 160Range = 160 - 70 = 90
30 + 80 = 110
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
From 80 to 110
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 - 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
100 + 30 + 80 = 210
The result of the equation - 100 plus 90 plus 60 plus 80, is found as follows; 100 + 90 + 60 + 80 = ( 100 + 90 ) + 60 + 80 = 190 + ( 60 + 80 ) = 190 + 140 = 330 Answer = 330
From 80 to 110
80 is. ------------------------------------------- The mean average is calculated by adding up the numbers and dividing by how many there are: mean average = (80 + 60 + 70 + 110) ÷ 4 = 320 ÷ 4 = 80
80+90+100=170+100=270
