The mathematical formulas for grades one to three are as follows:
The mathematical formulas for first grade:
Unit number addition and subtraction: a + b = c, a - b = d (a, b, c, d are unit numbers)
Number sequence: 1, 2, 3, 4, 5...
Addition and subtraction within ten: a + b ≤ 10, a - b ≥ 0
Second grade mathematics formula:
Addition within ten: a + b = c (a, b, c are within ten Numbers)
Subtraction within ten: a - b = d (a, b, d are numbers within ten)
Multiplication table: a × b = c (a, b, c is a number within ten)
Number sequence: 2, 4, 6, 8, 10...
Third grade mathematics formula:
Addition within ten: a + b = c (a, b, c are numbers within ten)
Subtraction within ten: a - b = d (a, b, d are numbers within ten) )
Multiplication table: a × b = c (a, b, c are numbers within ten)
Division table: a ÷ b = c (a, b, c c is a number within ten)

Knowledge expansion
Learning mathematics is a A task that requires patience and persistence, here are some ways to help you learn math effectively:
Understand the basics: Mathematics is a cumulative subject, so make sure you have a good understanding of the basic concepts first . If necessary, review some basics to build a solid mathematical foundation.
Build a solid foundation in mathematical thinking: Mathematical thinking is the key to solving mathematical problems. Develop logical thinking, abstract thinking and reasoning skills by doing exercises and solving problems.
Make a study plan: Make a reasonable study plan and study according to the plan. Courses and study time can be arranged according to personal learning situation and goals to ensure that there is a certain amount of study time every day.
Actively participate in classroom learning: Actively ask questions and participate in discussions in class, and interact with teachers and classmates to better understand and master knowledge.
Do a lot of exercises: Mathematics is a practical subject, and doing a lot of exercises is an effective way to consolidate knowledge and improve skills. Choose exercises that suit your level and proceed step by step from simple to complex.
Seek help: If you are stuck or don’t understand something, it’s important to ask for help. You can ask teachers, classmates or mathematics communities for advice, or you can find relevant reference books and online resources.
Pay attention to mathematical practice: applying mathematics to practical problems is an important way to consolidate and improve mathematical skills. Try to solve practical problems, such as applying mathematics to daily life or other subjects.
In short, learning mathematics requires persistent efforts and hard training. Through reasonable learning methods and unremitting efforts, I believe you will be able to achieve good mathematics results.
