5⋅5⋅5⋅2⋅2⋅2=? 5\cdot5\cdot5\cdot2\cdot2\cdot2=? 5⋅5⋅5⋅2⋅2⋅2=?
We use the substitution property and organize the exercise in the following order:
5×2×5×2×5×2= 5\times2\times5\times2\times5\times2= 5×2×5×2×5×2=
We place parentheses in the exercise:
(5×2)×(5×2)×(5×2)= (5\times2)\times(5\times2)\times(5\times2)= (5×2)×(5×2)×(5×2)=
We solve from left to right:
10×10×10= 10\times10\times10= 10×10×10=
(10×10)×10= (10\times10)\times10= (10×10)×10=
100×10=1000 100\times10=1000 100×10=1000
