Poker game. Math problems in grade one. The little sun has its back to the little moon, so let the little moon operate in the following four steps: Step 1: Assign the left, middle and right.

I would have played this little game five years ago, but you made a mistake in the fourth step. The correct one should be (Step 4: After taking out three blocks from the right pile, take out the same number of blocks from the middle pile and put them on the right pile).

Let me give you an example:

Left, middle and right

For example: 1 5 5 5

The game begins: 2 left and 3 right in the middle. At this time, there are two left on the right. At this time, take two from the middle and put them on the left.

Finally, there is 8 in the middle (conclusion put the middle number x2 on the right+put the middle number on the left).

3X2+2=8

Example 2 Left, Middle and Right Side

×××

X-3 X+5 X-2

Left 3 right 2, into the middle, with X+5 in the middle, and then X-2 on the right, so the number of sheets in the middle is.

X+5-(X-2)=7.

The number of sheets placed on the right side of rule X2 plus the number of sheets placed on the left side is the middle number of sheets 7.

2X2+3=7
