1: \(\left(-16\right)\cdot10=-\left(16\cdot10\right)=-160\)
2: \(23\cdot\left(-5\right)=-\left(23\cdot5\right)=-115\)
3: \(\left(-24\right)\cdot\left(-25\right)=24\cdot25=600\)
4: \(\left(-12\right)^2=12^2=144\)
5: \(18\left(-12\right)=-18\cdot12=-216\)
6: \(-18\cdot0=-\left(18\cdot0\right)=-0=0\)
7: \(49\cdot\left(-76\right)=-\left(76\cdot50-76\right)\)
\(=-76\cdot50+76=-3800+76\)
=-3724
8: \(\left(-26\right)\left(-32\right)\)
\(=26\cdot32\)
\(=26\left(30+2\right)\)
\(=26\cdot30+26\cdot2=780+52\)
