This morning, my father and I went to the construction site to see an uncle. My uncle counted the logs on the playground, and the logs just piled into a trapezoid. When he saw us coming, he said, "You're just in time. Please help me count the wood!" I feel dizzy. "

I looked at it carefully and found that there was a pattern in this pile of wood. The bottom line is always one more line than the top line! That's easy. Add the number of roots in the top row and the number of roots in the bottom row, then multiply the obtained number by the total number of rows of wood, and finally divide it by 2 to get the total number of roots of wood. When I said this number, my uncle and father both smiled with satisfaction.

Today, my mother told me an interesting math story.

The story says: A mother pig took three little pigs to buy flowers. 20 yuan, a flower, mother pig wants to buy 60 flowers. So, mother pig asked three little pigs, "We want to buy 60 flowers, one in 20 yuan. How much will that cost? " The biggest pig said, "20 times 60 equals 1200 yuan, so it costs 1200 yuan!" " The second little pig said, "No! Don't! It's two tens times six tens equals twelve tens, which is 1200 yuan! The youngest baby pig went on to say, "I think you are all right, but in different ways, they are all the same." "That's right!" Mother pig praised.

When it's time to tie flowers, the youngest baby pig first asks, "Now it's time to help flowers. 12 flowers tied together. How many bundles can you tie? " Mother pig didn't make a sound, so everyone shook their heads and saidno. After a while, the biggest baby pig cried. "1200 divided by 12 equals 100, so you can tie 100 flowers."

"Although we are tied up, we still have to send flowers to 20 grandfathers. How many bundles will each grandfather divide? " The little pigs said. After 30 minutes, the little pigs said, "Oh! We know that 10020 = 5, so each grandfather is divided into 5 bundles! "

The baby pigs gave the flowers to grandpa, and grandpa quickly said thank you. Little pig and mother pig are very happy.

After listening to this math story, I like math even more, and I have strengthened my confidence in learning math well!
