Adding Near 10's
Today we have been adding 11, 12, 13, 21, 22 and 23 to a number. The methods we have been using are for +11 we add 10 then add 1, for +12 we add 10 then add 2, for +13 we add 10 then 3.
Do you think you could solve these calculations?
12 + 13 =
34 + 12 =
15 + 11 =
67 + 21 =
44 + 22 =
98 + 22 =
