All the time you spent memorizing multiplication tables(乘法表)may have made you a better mathematician, according to a new study. A team of scientists from Stanford University, in California, have shown how the brain reorganizes itself as kids learn math.

After a certain amount of time spent practicing math, kids can put away the calculator(计算器). They don’t even need to count on their fingers. They simply know the answers to subtraction(?), addition (+), and multiplication (×) facts. The quicker kids can recall basic math facts, the easier it is for them to solve more difficult math problems.

The Stanford University researchers observed(观察)the brain activity of 28 students, ages 7 to 9, for the study. They took scans of the students’ brains as the students solved math calculations without the help of a calculator, pen or paper. A calculation—three plus four equals seven, for example—flashed on a screen. The students pushed a button to say if the answer was right or wrong. The scientists also recorded the response speed, and what parts of the brain became active as the kids pushed the button.

These observations showed a process called fact retrieval. Rather than using their fingers to count, or scrawling out equations(列算式)on a piece of paper, the students pulled the answers from memory. It’s as if the answers to basic subtraction, addition, and multiplication problems are kept in a long-term storage part in the brain. The storage part was built from repetition. “Experience really does matter,” said Dr. Kathy Mann Koepeke of the National Institutes of Health.

Children make the changefrom counting to fact retrieval when they are 8 to 9 years old, the study says. This is the time when most students are learning basic addition and subtraction. When kids have basic math facts memorized, the brain has more free space to learn more difficult math.

This process has benefits for the future. The study showed, as kids got older, their answers relied more on memory and became quicker and more correct. Less brain activity was involved in counting. Some children make this change quicker than others.

Scientists hope to use this research to develop new strategies(策略)to help kids learn math at all levels. One strategy the study suggests is for students to test themselves in different orders—solving five times three before five times two, for example. Mixing up the order keeps the brain active. Keep these trainings up, and you may be a math whiz in no time.

My best friend and I made our first trip to Ireland less than a year ago. I wasn’t very excited about it at the very beginning. But my uncle wanted me to visit Ireland and offered to pay for my trip. Then I did. All of the words “magical, charming and memorable” don’t even describe what Ireland is. Our favourites were Kilkenny, Cobh and Killarney. We did a self-driver tour.

We stayed in a castle in Dublin for two days, where my ancestors(祖先) came from. The town we thought we might be bored in was Kilkenny, but we loved every minute we were there. There were so many places to explore and the pictures we took were beautiful.

It was so exciting to see the little village of Cobh and know it was the last stop for the Titanic(a famous ship) at that time. We loved the visitor centre there and the little shops. We never got any bad food there. It was so mouth-watering at every stop! And when we stayed in Westmeath, we saw the Trim Castle through the windows and found some scenes from Brave Heart which was filmed there. We were so excited. Again, more beautiful pictures were taken in that tiny town.

We love the country, the people, the food and the magic. We would go back very soon. I was so thankful for my uncle who had given me the chance to be there.

I have no words to adequately describe our trip. Go, explore the small villages, eat and enjoy! I still look at my pictures and can’t believe I was actually there.
