Mathematics has obvious peculiar regularity, and the differences need to go deep into the mathematics behind it. Once students dig deep into their own mathematical principles, they will find that mathematics is everywhere, so beautiful and so secret.
Examples of building pagodas in primary school mathematics;
In mathematics, some formulas are very regular, such as1x9+2 =1,12x9+3 =11,/kloc-0.
1X9+2= 1 1？
12x 9+3 = 1 1 1？
123 x9+4 = 1 1 1 1？
1234 x9+5 = 1 1 1 1 1？
12345 x9+6 = 1 1 1 1 1 1 1？
123456 x9+7 = 1 1 1 1 1 1 1 1？
1234567 x9+8 = 1 1 1 1 1 1 1 1 1？
12345678 x9+9 = 1 1 1 1 1 1 1 1 1 1？
123456789 x9+ 10 = 1 1 1 1 1 1 1 1 1 1？
How harmonious and regular, just like a pagoda.
