What happens in your head when you calculate 27+38?

Be honest, Mr Jackson was our math teacher.

And that's the real reason I have lost my appetite for math.

I add the 10s digits together first, then I add the units together, then add both sums to each other.

That's 50 plus 15 so 65 .

Add the 10s then the ones.

And I feel the same way about the years.

20 + 30 = 50
7+8=15
50+15=65

20+30 = 50
7+8 = 15
50+15 = 65

27 + 38
= (27 + 3) + (38 - 3) // make the first number easier to add to.
= 30 + 35
= 65

Making me use my brain too early
