1. Using the distribution law, divide 24 into the product of two numbers, for example, 24=3×824=3×8, 24=4×624=4×6, etc. In this way, more multiplication formulas can be obtained, such as: 3×8=8×3=24=4×6, etc.
2. Use commutative law to change the order of numbers in multiplication formula, such as: 24= 12×2=2× 12, 24=8×3=3×8, etc. In this way, more multiplication formulas can be obtained, such as: 12×2=24, 2× 12=24, 8×3=24, 3×8=24, etc.
3. Multiply the results of multiple numbers with other numbers by using the associative law, such as: (3×4)×2=24=(3×4)×2=24, (4×2)×3=24=(4×2)×3=24, etc. In this way, more multiplication formulas can be obtained, such as: (3× 4 )× 2 = 24 = (3× 4 )× 2 = 24 = (4× 2 )× 3 = 24 = (4× 2 )× 3 = 24 and so on.
4. By factorization, 24 is decomposed into the product of two numbers, for example, 24= 1×24=24= 1×24, 24=2× 12=24=2× 12. So we can get more multiplication formulas, such as: 1×24=24= 1×24=24, 2× 12=24=2× 12=24, 3× 8 = 24 = 3×
5. Through the above methods, we can get many multiplication formulas with the product of 24, which can help us better understand and master the law of multiplication. At the same time, these extended multiplication formulas can also be used in the calculation of practical problems to improve our calculation ability and problem-solving ability.
Historical significance of multiplication formula
1, multiplication formula is a basic operation mode in mathematics, which has far-reaching historical significance. First of all, multiplication provides a quick way to find the sum of several identical addends. For example, 3*4 can be expressed as the sum of 4 3s and 4 times of 3.
2. From the philosophical point of view, multiplication is actually the result of qualitative change caused by additive quantity. For example, when we need to calculate five 3-plus results, it will be quite tedious to add five times directly, and multiplication provides a concise solution. Multiplication formula is also the basis of constructing complex mathematical theories and formulas.
