2 x 783 x 5 = 783 x (5 x2) = 783 x 10= 7830
4 x 75 x 25 = 75 x (4x25) = 75 x 100= 7500
25 x 4 x 84 = 84 x (25x4) = 84 x 100= 8400
2 x 798 x 5 = 798 x (2x5) = 798 x 10= 7980
5 x 996 x 2 = 996 x (5x2) = 996 x 10= 9960
783×5×2=783×(5×2)=783×10=7830
75×25×4=75×(25×4)=75×100=7500
84×4×25=84×(25×4)=84×100=8400
798×5×2=798×(5×2)=798×10=7980
996×5×2=996×(5×2)=996×10=9960
