Is there a program for voicing mathematical tasks for mental counting?

Question

Mathematics

There was a math teacher at school who liked to make a competition for us at the beginning of the lesson for 1 minute. She quickly gave us verbal tasks, such as addition, multiplication, division. And at the end we must answer. Whoever said it right first got 5 in the magazine. For example, she spoke very quickly verbally 73+21*5-38+9-26*2/3+4. She spoke quickly. And then immediately: "Speak your answer." One guy always wins.
Now to train the brain like that.
Has anyone come across such a program or browser extension? To give you a sound example?
