if there are that many things missing then go left to right; 5+1 then multiply the sum by ten

5+1=6
6x10=60

I hope I was helpful
yes just use wat you learned with PEMDAS 
Since you dont have parenthesis or exponents or the division 
just do 1x10 first and you get 10 then you do 5+10 = 15 
so for the example you set it would be 15
