We need to estimate the result of 1 120 divided by 59 by oral calculation. To help us understand and estimate, we can try to find out the result of 120 divided by 59, and then use this result to estimate the result of 1 120 divided by 59.

Suppose 120 is divided by 59 and the result is a. Then, we can get the following equation: 120 ÷ 59 = a. To get the result of 1 120 divided by 59, we can put1/kloc-0.

Now, we need to calculate the value of a, and then use this value to estimate the result of 1 120 divided by 59. 120 divided by 59 is about 2.03. So by estimation, the result of dividing 1 120 by 59 is about 20.

Learning methods of learning mathematics:

1, preview: before class, browse the contents of the unit that the teacher will teach, and pay attention to the parts that you don't understand.

2. Listen carefully: There are many new definitions of terms or new ideas at the beginning of the new course. The teacher's explanation must be clearer than the students' own reading. Be sure to listen attentively, don't be smart and make mistakes, and more importantly, learn and cultivate your thinking ability.

3. After-class exercises: focus on finishing: On the evening of math class, we should sort out the contents taught that day, and memorize definitions, theorems and formulas. Some students think that mathematics focuses on reasoning and does not need to recite anything. This concept is incorrect.

Generally speaking, rote learning means not rote learning. It doesn't mean that you don't need to memorize some basic definitions, theorems and formulas. You need to master some problem-solving skills and ideas through practice.
