There are 12 digital cards to be distributed to pigs, kittens and bears, each with four cards, and the sum of the numbers on the four cards should be equal. How to divide it?

The arithmetic problems of senior one are as follows:

Piglet: 1 7 8 10

Kitten: 3 5 6 12

Bear: 2 4 9 1 1

Divide cards, mainly to make the sum on their cards equal, so you must be familiar with digital operation.

Extended data addition (usually indicated by the plus sign "+") is one of the four basic arithmetic operations, and the others are subtraction, multiplication and division. For example, in the picture below, * * * has a combination of three apples and two apples, and * * * counts as five apples. This observation is equivalent to the mathematical expression "3+2 = 5", that is, "3 plus 2 equals 5".

Addition has several important properties. It is interchangeable, which means that the order is not important, it is interrelated, which means that when more than two numbers are added, the order in which the addition is performed is not important. Repeatedly adding 1 is the same as counting; Adding 0 will not change the result. Addition also follows related operations such as subtraction and multiplication.
