$3\mathrm{.}9$ LAB: Arithmetic expression $-$ ADD$/$SUB$/$MUL

Given the mapping of registers to variables below, write a program in LEGv$8$ to implement the following expression: Z $=($A$+$B$)$ X $($C$-$D$)3\mathrm{.}9$ LAB: Arithmetic expression $-$ ADD$/$SUB$/$MUL

Given the mapping of registers to variables below, write a program to implement the following expression:

Ex: If the values of $x9,x10,x11,$ and $x12$ are initialized in the simulator as:

the result is stored in $x19$ :

Note: Use the $\text{'}+\text{'}$ button under the Registers display to initialize register values.
