Simple calculation
Simple calculation is a special kind of calculation, which makes use of the algorithm and the basic properties of numbers, thus making the calculation simple and making it easy to calculate numbers from very complicated formulas.
exclusive of
That is, recursive calculation requires a series of step-by-step calculations. Calculate multiplication and division first, then addition and subtraction. In the successive calculation of multiplication and division, it should be calculated from left to right. Among the four operations, addition and subtraction are called primary operations, and multiplication and division are called secondary operations.
Matters needing attention
When performing simple operations (four operations), we should pay attention to the relationship between operation symbols (multiplication, division, addition and subtraction) and big, middle and small brackets. Don't skip the operation to avoid mistakes.
Powder companion
The most commonly used method in simple calculation is multiplication and distribution law. The law of multiplication and distribution means ax(b+c)=axb+axc, where A, B and C are arbitrary real numbers. On the contrary, axb+axc=ax(b+c) is called the inverse application of multiplication and division (also called finding common divisor), especially when A and B are complementary to each other, this method is more useful.

Simple Decimal Calculation Problems with Answers in the Fifth Grade of Primary School
The case of simple decimal calculation in the fifth grade of primary school is as follows: calculation skills: when two numbers A and B are multiplied at the same time or the same number C is added and subtracted, you can add and subtract the two numbers A and B first, and then multiply and divide them with C. As follows: 0.5 ÷ 2-0.15 ÷ 2 = (0.5-0.65433) 0.5x2-0.15x2 = (0.5-0.5) Calculation skills: When the conditions of addition, subtraction, multiplication and division are different from the above example, that is, four abcd. Calculation skills: between big, small and medium brackets and multiplication, division and addition, first calculate the number in brackets, then calculate the number in braces, and finally multiply, divide and add the number outside brackets, as follows: 30.8 ÷ [14-(9.85+1.07)] = 30.8. Extended data:
Simple calculation: Simple calculation is a special kind of calculation, which makes the calculation simple and easy to calculate the final number from a very complicated formula by using the algorithm and the basic properties of numbers. Off-type calculation: recursive calculation, which requires a series of numbers to be calculated step by step. Calculate multiplication and division first, then addition and subtraction. In the successive calculation of multiplication and division, it should be calculated from left to right. Among the four operations, addition and subtraction are called primary operations, and multiplication and division are called secondary operations. Multiplication distribution law: the most commonly used method in simple calculation is multiplication distribution law.
