The solution to the example of frog jumping in the first volume of mathematics in senior one is to observe whether the frog jumps left or right on the number axis. If you jump to the left, look at the largest number on the far right first. For example, the largest number on the far right is 12, so he jumps three squares to the right, then jumps four squares to the right, and finally he can solve the problem, that is, twelve MINUS three MINUS four, and then the final result is equal to five. So the remaining five paragraphs did not jump, but jumped to the left. If you jump to the right, you need to see how many paragraphs he jumped to the right first. If you jump three paragraphs to the right, two paragraphs to the right, and two paragraphs to the right, then the final formula is three plus two plus two, and the final answer is five, so this is an example of frog jumping in the first volume of senior one, that is, a solution to jumping on the number axis, mainly depending on whether to jump left or right.
