Question

Add :$t-8tz,3tz-z,z-t$

Answer 1

To add : $t-8tz,3tz-z,z-t$

On combining the like terms and adding them we get

$\begin{array}{rcl}& =& t–8tz+(3tz–z)+(z–t)\\ & =& t–8tz+3tz–z+z–t\\ & =& t–t–8tz+3tz–z+z\\ & =& t(1–1)+tz(-8+3)+z(-1+1)\\ & =& t\left(0\right)+tz(-5)+z\left(0\right)\\ & =& –5tz\end{array}$

Hence, On adding $t-8tz,3tz-z,z-t$ we get $-5tz$.
