Song of Mathematicians

The original song is the theme song of the anime "Doraemon."
Everyone is useless but I can solve it all
My math skills are so good that I never fall

Multiplication, division, so easy to me
Addition and subtraction, all filled with glee

Integration brings joy and fruitful gain
Enter a marvelous matrix, answers I attain

Magical functions, beyond belief
With a touch, secrets unfold without any grief

Trying to turn decimals into whole numbers, but it's just a show
Take a look, Maths has arrived
Maths, oh everyone loves you
Even the teachers, they are proud too

In the lyrics, there are a total of ten mathematical terms. How many do you recognize?
