Multiplication is a basic operation in mathematics, which is to add a number several times. In this problem, we need to calculate the result of 80 times 660.
We can decompose 660 into 600 and 60. So we can multiply 80 by 600 and then add the result to 80 by 60.
80 times 600 equals 48,000. Next, we will add 48000 and 80 times 60. 80 times 60 equals 4800. Add these two results together and you get 48000 plus 4800, which is 52800. So, 80 times 660 equals 52800.
Multiplication is a basic mathematical operation that can help us solve many practical problems. For example, if we want to buy 660 apples, and the price of each apple is 80 yuan, then we need to pay 52,800 yuan. This is the practical application of multiplication.
The importance of multiplication algorithm;
1, Simplify calculation: The algorithm of multiplication calculation can help us simplify complex multiplication calculation and make the calculation process simpler and more efficient. For example, commutative law and associative law can simplify the calculation steps without considering the order and combination of factors in multiplication calculation.
2. Cultivate logical thinking: the operation law of multiplication calculation requires us to follow certain logical rules. For example, the exchange law and the association law require us to calculate in a certain order, and the distribution law requires us to split and combine different numbers flexibly. By studying and applying the operation law of multiplication, we can cultivate our logical thinking and reasoning ability
3. Improve efficiency: The algorithm of multiplication calculation can help us improve the calculation efficiency. For example, when calculating the product of a large number of data, we can use the distribution law to split the product into multiple parts for calculation, thus reducing the number of calculations and time.
4. Cultivate the sense of innovation: The algorithm of multiplication calculation is an innovative achievement, which does not exist naturally, but is obtained through the exploration and creation of human wisdom. By studying and applying the operation law of multiplication calculation, we can cultivate our own innovative consciousness and creativity, so as to better solve various mathematical problems.
