Anonymous users2024-02-08According to the question, the simple calculation method used in this problem is to merge the same terms after the denominator becomes the same, the original formula = 8 68 + 51 68 + 20 68 = (8 + 51 + 20) 68 = 79 68.

Anonymous users2024-02-07This simple calculation doesn't make much sense.
Add 2/17 and 5/17 first to get 7 17
But the result is 7/17 and 3/4 still have to be scored.

Anonymous users2024-02-03Summary. Hello dear kiss 125 * 3 * 25 * 32 = 125 3 25 4 8 = 125 8 25 4 3 = 1000 100 3 = 300000
125*3*25*32 easy calculation.
Hello kiss 125*3*25*32=125 3 25 4 8=125 8 25 4 3=1000 100 3=300000 The simple algorithm for this branch is to divide 32 into 4 8, and then multiply it with 125 and 25.
Hello dear kiss, expand knowledge first multiplication and division, then add and subtract, and those with parentheses are counted in parentheses first. The rules of integer addition and subtraction: 1) to align the same digits, and then add or subtract the numbers rolled earlier on the same counting unit; 2) Whoever reaches the age of ten will advance to the previous one.
2. The calculation rules of decimal addition and subtraction: 1) calculate the decimal addition and subtraction, first align the decimal point of each number (that is, the number on the same destroyed number) to prepare the macro, 2) and then calculate according to the law of integer addition and subtraction, and finally align the decimal point on the horizontal line in the number. (There is a 0 at the end of the decimal part of the number, and the 0 should be removed in general.) ）

Anonymous users2024-02-02This problem can be easily calculated using the method of adding brackets. It should be pointed out that the parentheses are added after the minus sign, and the numbers in the brackets must change the symbol, the number that was originally the minus sign should be rewritten as a plus sign, and the number that was originally a slow plus sign should be rewritten as a minus sign.
It is directly 4 9 times (1-5 6) + 1 2 = 4 9 times 1 6 + 1 2 = 2 27 + 1 2 = 4 54 + 27 54 = 31 54.
128 23 23 27 27 How do you calculate simple arithmetic? First of all, the two multiplication formulas with the common factor 23 can be written first, 23 multiplied by the parentheses 128-27 brackets minus 27, you can calculate the multiplier 23 100, add 23, subtract 27, that is, equal to 2300-4, equal to 2296
4 9 3 10 5 9 Easy arithmetic?
Of course, this is to adjust the 5 9 in the back to the front, and add it to 4 9 first, so that you get 4 9 + 5 9 + 3 10, and then you get 9 9 + 3 10, which is 1 + 3 10, which is equal to one and 3 10 >>>More
<> directly convert 24 into fractions for approximation, and finally multiply 32 by 16 to perform simple calculations.
1.Commutative law of addition: a+b=b+a
Two additions swap positions, and the sum is invariant, which is called the commutative law of addition. >>>More
