Question

123×18-123×3+85×123.简便计算怎么做？

Answer 1

123×18-123×3+85×123
=123×(18-3+85)
=123×100
=12300
根据乘法分配律计算a×b+a×c=a×(b+c)

Answer 2

123×18-123×3+85×123
=123×(18-3+85)
=123×100
=12300
根据乘法分配律计算a×b+a×c=a×(b+c)

Answer 3

123×18-123×3+85×123
=123×(18-3+85)
=123×100
=12300
根据乘法分配律计算a×b+a×c=a×(b+c)

Answer 4

123×18-123×3+85×123
=123×(18-3+85)
=123×100
=12300
根据乘法分配律计算a×b+a×c=a×(b+c)

Answer 5

one hundred and twenty-three × 18 - 123 × 3 + 85 × 123 = 123 × (18 - 3 + 85) = × 100 = 12300 по множительному распределению × B + a × C = a × B + c)
