1, clever addition

Addition is one of the most basic operations in mathematics. In addition, students can use the following methods:

(1) rounding method: When adding two numbers, first observe whether they are close to an integer or integer ten digits. If they are close, they can be added first and then added with other numbers to simplify the calculation process.

For example: 23+18+20 = 23+20+18 = 61.

(2) Split method: When the sum of two numbers is close, it can be split into the sum or difference of two numbers, and then added or subtracted with other numbers to simplify the calculation process.

For example: 32+39 = (30+2)+(40-1) = 71.

2. Subtraction calculation

Subtraction calculation can help students solve subtraction problems faster. Here are some common subtractions:

(1) split method: split a number into the sum or difference of two numbers, and then subtract or add the sum or difference of these two numbers with another number to simplify the calculation process.

For example: 63-27=(60+3)-(30+7)=36.

(2) Complement method: Find the complement of a number, then add or subtract this number from another number, and then subtract or add this complement to simplify the calculation process.

For example: 54-26=(54+4)-(26+4)=30.

3. Clever calculation of multiplication

Clever multiplication can help students complete multiplication operation faster. Here are some common multiplication methods:

(1) grouping method: divide the factors of two numbers, then multiply them respectively, and then combine them to get their.

For example: 2× 4 = (/kloc-0 /× 2 )× (2× 2) = 4× 4 =16.

(2) Split method: Split a number into the sum or difference of two numbers, and then add or subtract the product of two numbers with another number to simplify the calculation process.

For example: 5× 7 = (5+5 )× (7-1) =10× 6 = 60.
