怎样用简便方法计算这道题？

36×77+36×22×36
=36×11×(7+2×36)
=36×11×79
=36*11*(80-1)
=396*80-396
=31284

解：原式=36×(77+22×36)
＝36×（77+20×36+2×36）
=36×（77+720+72）
=36×869
=36×870-36
=36×800+36×70-36
=28800+2520-36
=31320-36
=31284

36×77+36×22×36
=36×11×(7+2×36)
=36×11×79
=31284

36×77+36×22×36
=36×11×(7+2×36)
=36×11×79=31284

提取公因式36×11

36×77+36×22×36
=36×11×(7+2×36)
=36×11×79=31284

36*(77+22*36)
