Ilia_Sergeevich [38]

Answer:

56-7m

Step-by-step explanation:

l7m–56l m<8

so then it would be...

l 7 * 7 - 56 l=

l 49-56 l = l -7 l

but the absulute value of -7 is 7, so how does this help us? well lets see

56-49= 7  this proves that all we have to do is  switch the order giving us the solution 56-7m

hope this helped :)
