Description
"Operations of Numbers" general review PPT courseware
To add and subtract integers, align the same digits; to add and subtract decimals, align the decimal points; to add and subtract fractions, divide them into fractions with the same denominator. Can you talk about the connection?
How to perform arithmetic operations with integers, decimals and fractions?
Operations at the same level, from left to right
For operations above two levels, calculate multiplication and division first, then addition and subtraction. If there are parentheses, calculate the parentheses first.
The changing rules of sum:
1. Add a number to the addend, and add this number to the sum.
2. One addend is added to a number, and the other addend is reduced by the same number. The sum remains unchanged: 6+7=13 6+A+7-A=13
The changing rules of sum:
1. Add a number to the addend, and add this number to the sum.
2. One addend is added to a number, and the other addend is reduced by the same number. The sum remains unchanged: 6+7=13 6+A+7-A=13
The changing rule of product:
1. If a factor is expanded by A times, the product will also be expanded by A times. If two factors are expanded by A times at the same time, the product will be expanded by A² times.
2. One factor is expanded by A times, and the other factor is reduced by A times, but the product remains unchanged.
The changing rules of quotient:
1. The divisor remains unchanged, the dividend is expanded by A times, and the quotient is also expanded by A times.
2. If the dividend remains unchanged and the divisor is expanded by A times, the quotient will be reduced by A times.
2. The dividend is expanded by A times, the divisor is reduced by A times, and the quotient remains unchanged.
