I finish my Maths exam early and look at all the calculations I have done so far in my Scientific Calculator (using the up arrow thing). Here are some.
7 * 3 = 21
16 - 4 = 12
12 * 2 = 24
23 - 7 = 16
2000 + 1000 = 3000
2000 / 2 = 1000

.
Moral : It's high time I started learning simple addition and subtraction. Again.
