7.23 + 6.84 + 0.84 + 2.77

7.23 + 6.84 + 0.84 + 2.77


7.23+6.84+0.84+2.77
=(7.23+2.77)+6+(0.84+0.84)
=10+6+0.84*2
=16+1.68
=17.68



34.5*6.23-34.5+1.77*34.5
Simple calculation


Original formula = 34.5 * (6.23-1 + 1.77)
=34.5*7
=241.5



The best way to calculate 0.23-2 / 7 + 0.77-5 / 7 is


Original formula = (0.23 + 0.77) - (2 / 7 + 5 / 7)
=1-1
=0



5 and 5 / 5 minus (1.23-1 and 1 / 6) - 1.77 =?
I'm sorry. It should be 5 / 6


5 and 5 / 5 - (1.23-1 and 1 / 6) - 1.77
=6-1.23 + 1 and 1 / 6-1.77
=7 and 1 / 6 - (1.23 + 1.77)
=4 and 1 / 6
