Are the following terms correct?
1) One plus one equals two.
2) to make a detailed multiplication, are these terms correct?
3 X 15 = 45 --> 3 times 5 equals 15. I write 5 and I store (= correct?) 1. three times one equals three. 3 plus 1 equals four. so, three times fifteen equals forty-five.
We said 'carry a one' too (raising a thumb if we weren't using writing it down). Also (because it's easily reinforceable by gesture, when teaching a young child) "keep the 1 in your head" [pointing].
But as you say, the terminology may have changed now. As they use calculators from a (ridiculously) early age, they may well say 'store'.
