[quote=Anonymous][quote=Anonymous][quote=Anonymous]23+10 2 tens 3 ones plus 1 tens What is 2 tens and 1 tens? 3 tens So it’s 30. Then add 3 ones. 30+3= 33. You call this easy? Or 92-20 9 tens 2 ones minus 2 tens What is 9tens minus 2tens? 7 tens That’s 70. Oh don’t forget to add 2 ones to that. That’s 72! You call this easy? [/quote] At this point I showed my kid the “secret” strategy of standard algorithm. The key is to be very clear aligning the numbers on the right These are easy because there is no carry over.
