It’s kind of hard to explain this without being one on one, but I’ll give it a try.

25) With numbers like 8 and 13, I think this way, 3+8=11+10=21.

Then 21+7=28. Finally, 28+10=38+2=40. If you break it down into numbers that you can add easily in your head, it’s quite simple.

26) This one is easy. 2×25=50×4=200.

27) I’ll do one more. 5×8=40×10=400 now think of 2×40=80 and 400+80=480

Try it. You’ll get the hang of it.
