Answer 1

Dear Student,

$$\begin{gathered} a)\left(-3\right)\times \left(+5\right) \\ as\left(-1\right)\times \left(+1\right)=-1 \\ Henceweget\left(-3\right)\times \left(+5\right)=-\left(3\times 5\right) \\ =-15 \\ b)\left(-7\right)\times \left(-3\right) \\ as\left(-1\right)\times \left(-1\right)=+1 \\ Henceweget\left(-7\right)\times \left(-3\right)=+\left(7\times 3\right) \\ =21 \\ c)\left(+8\right)\times \left(-5\right) \\ as\left(+1\right)\times \left(-1\right)=-1 \\ Henceweget\left(+8\right)\times \left(-5\right)=-\left(8\times 5\right) \\ =-40 \\ g)0\times \left(+2341\right) \\ as0\times anything=0 \\ henceweget0\times \left(+2341\right)=0 \\ h)0\times 0 \\ =0 \\ similarlyyoucansolvetheotherparts. \end{gathered}$$
