cement christian jewelry wholesale The opposite number of 3, that is, the opposite number of negative 3, is positive, equal to 3. -(-3) = 3 Im method: The additional method of one digit: two digits of one digit, you can directly use the number of methods to find harmony. usually compiled the results of two digits into the addition table. Multi -digit addition: The same number of numbers. Which one is full of the number, and then one step forward. Multi -digits plus multi -digit, you can first write two multi -digits into the form of different count units. The number of countless units is added according to the calculation law and one -digit law law.
If the method of adding method: When using the "cutting method" in the addition or subtraction, directly add or decrease from the left high (at the same time (at the same time Pay attention to whether the next one needs to be in and misaligned), know the answer to the accuracy of the option requirements. When using the "Crossing Law" in the multiplication or division method, in order to make the results as accurate as much as possible, pay attention to the approximate direction of the intercept: . A multiplier factor in expanding (or reduced) a multiplication factor, you need to shrink (or or Expand) another multiplication factor. . The extension of the extension (or reduction) needs to be extended (or reduced). If you find the sum of the two pilots (ie, A*B /- C*D). . On one side of the increase (or reduced) the number of the number, the other side of the addition (or expansion) needs to be reduced. . The side of the expansion (or reduction) reduction number needs to be expanded (or reduced) the other side of the minus number.
