Question

thực hiện phép tính

(23*37-37*11):37

Answer 1

\(=\left[37.\left(23-11\right)\right]\div37\)

\(=\left[37.12\right]\div37\)

\(=444\div37=12\)

Answer 2

\(\left(23\times37-37\times11\right):37\\ =\left[37\times\left(37-11\right)\right]:37\\ =37\times12:37\\ =37:37\times12=1\times12\\ =12\)
