-5 s
Thinks about your #s# to be a 1 # -1 xx 5# = -5 Therefore, you have -5s
#-5s#
Multiplication is the short cut for repeated addition.
So #3+3+3+3+3# can be written as #5 xx3#
#x+x+x+x+x+x+x# can be written as #7 xx x#
In this case we have #-s-s-s-s-s# which can be written as #5 xx (-s)#.
This simplifies to #-5s#
How do you simplify #-s-s-s-s-s#?
