Addition combines quantities to find a total, from single-digit sums to multi-digit column addition with carrying.
Every later topic — money, measurement, algebra — sits on fluent, accurate addition.
When a column adds to 10 or more, you write the units digit and carry the tens digit into the next column on the left.
Add the numbers again in the opposite order — addition gives the same total whichever way round you go.
