Simple calculation: 1, 8.32 * 34 + 8.32 * 66 2, 37.5/25 + 62.5/25 3, 7.25-0.68-6.25

Simple calculation: 1, 8.32 * 34 + 8.32 * 66 2, 37.5/25 + 62.5/25 3, 7.25-0.68-6.25


8.32×34+8.32×66
=8.32×(34+66)
=8.32×100
=832
37.5÷25+62.5÷25
=37.5×1/25+62.5×1/25
=(37.5+62.5)×1/25
=100×1/25
=4
7.25-0.68-6.25
=7.25-6.25-0.68
=1-0.68
=0.32



57×38+58×57.


57×38+58×57=57×(38+58)=57×1=57.
