Đáp án + Giải thích các bước giải:
`(-93) × 11 = ( -93 ) × ( 10+1 )`
`=(- 93) × 10 + ( - 93 ) × 1`
`= (-930) + ( - 93 )`
`= -1023 `
` 341 × (-21) = 341× ( - 20 - 1 )`
`= 341 × ( -20 ) - 314 × 1`
`= -6820 + 314`
`= -7161 `
`(-35) × 101 = ( -35 ) × ( 100 + 1 )`
`= ( -35 ) × 100 + ( -35 ) × 1`
`= - 3500 + ( -35 )`
`= -3535 `
` 29 × (-99) = 29 × ( - 100 + 1 )`
` = 29 × ( -100 ) + 29 × 1`
`= - 2900 + 29 `
`= - 2871 `
