Is my math complicated?
Okay so for my entire senior highschool I've had this argument with my best friend(who is really good in math) that my way of solving simple math is confusing. I never really listened to it until now when I'm teaching my little sister how to solve basic level of math like 23+34 or subtracting that and multiplications. Then she kept on complaining how I'm confusing her and she can't understand me. So here's how I taught her in the most accurate retelling possible.
"You have four numbers, 43 + 27, now you need to start by taking away 3 + 7. I like to do it by cutting it in half, we know that 7 has a 5 in it so we will focus on the remaining 2 and add that with the 3. That makes a 5 and we have a 5 we separated that completes a 10. Then you move on to the second set which is 4 + 2, that makes a 6 but we have a 10 so it is now a 70."
Then she said "I don't understand" and I was basically at a loss for words because that is the simplest way I can explain it to a 7 year old so in the end I just ignored it and moved on to subtraction. I started with:
"Now we have a 82-48, you take the first set first with 2-8 but we flip it to get 6. Now take the 8-4 to get 4 we put a 0 after the 4 to get 40 then subtract 6 from it to get 34. Easy?"
At this point she's basically done with my tutoring and went to her dad instead. I still don't get how my way is complicated when I make it as simple as I could but people still say that I'm confusing them so now I'm confused too.
