Wonderful effort with the strategy of Equal Addition. This is not PVP, although all the Maths strategies we learn, have an element of PVP because they all need you to round numbers to the nearest tidy number.
One other comment - you have use +7 in one of your problems. We would not normally do this, as we would round to the nearest tidy number - so you should have gone -3 on both sides rather than +7.
