Answer:
Let's do the math :
5x5=25+5=30 the reason you would put 5x5+5 is because it's the first part of the equation know that you have 30 we move on 5x5=25-15=10 know you have the second part of the equation. You also know what to divide.
30÷10=3 there's your answer hope this helped even though it's really late!!!
