assembly – To multiply and then add four double precision point values through MIPS

I am assigned to write a program that should multiply and then add four double precision points values in MIPS I wrote the following code,

.data
    doubleval1: .double  7.2
    doubleval2: .double 6.7
    doubleval3: .double 3.3
    doubleval4: .double 1.2
.text
    l.d $f0,doubleval1 
    l.d $f2,doubleval2 
    mul.d $f12, $f0, $f2
    li $v0, 3
    syscall
    
    
    l.d $f4,doubleval3
    l.d $f6,doubleval4
    mul.d $f12, $f4, $f6
    li $v0, 3
    syscall

This code multiply all the predefined inputs, I want to ask can I add them all together? as it is the question requirement “then add four double precision points values”, Thank you.
