Old math vs new math for addition. The traditional way stacks numbers in a column and carries to the next place. The newer way breaks numbers apart or uses a number line, like 37 + 48 → 30 + 40 = 70 and 7 + 8 = 15, then 70 + 15 = 85. Both give the same answer, but the new way helps students see place value and how the numbers combine. #oldmath #newmath #realmathvsnewmath
