$1-$ a$)$ Write a program which gives the summation of three numbers specified by the user at runtime

We'll write a program named add.asm that computes the difference of two numbers specified by the user at runtime, and displays the result on the screen.

The algorithm this program will follow is:

Read the three numbers from the user. We'll need three registers to hold these two numbers. We can use $ to and $$t1$ for this.

a$.$ Get first number from user, put in to $$t0.$

i$.$ load syscall read$\_$int into $$v0,$

ii$.$ perform the syscall, iii. move the number read into $$t0.$

b$.$ Get second number from user, put into $$t1$

i$.$ load syscall read$\_$int into $v$0,$

ii$.$ perform the syscall, iii. move the number read into $$t1.$

c$.$ Get third number from user, put into $$t2$

i$.$ load syscall read$\_$int into $$v00,$

ii$.$ perform the syscall, iii. move the number read into $$t2.$

Compute the summation $$t0+$$$+1+$$$+.$ We'll need a register to hold the result of this summation. We can use $$t3$ for this.
