Question

15x(-236)-235x(-15)

Answer 1

`@` `\text {Ans}`

`\downarrow`

`15 \times (-236) - 235 \times (-15)`

`= 15 \times (-236) + 235 \times 15`

`= 15 \times (-236 + 235)`

`= 15 \times (-1)`

`= -15`

Answer 2

\(15\times\left(-236\right)-235\times\left(-15\right)\)

\(=15\times\left(-236\right)-\left(-235\right)\times15\)

\(=15\times\left[\left(-236\right)+235\right]\)

\(=15\times\left(-1\right)\)

\(=-15\)
