例1下面有两盒蜡笔是小亮的。他最少有多少支蜡笔?他最多有多少支蜡笔?思路点睛:从图中可以看出,第1盒蜡笔有5支,第2盒蜡笔有6支,第3盒蜡笔有8支。因为有两盒蜡笔是小亮的,所以小亮的蜡笔既可能是第1盒与第2盒,也可能是第1盒与第3盒,还可能是第2盒与第3盒。把它们分别加起来,得到:第1盒与第2盒:5+6=11(支)第1盒与第3盒:5+8=13(支)第2盒与第3盒:6+8=14(支)
There are two boxes of crayons under Example 1 that are small and light. How many crayons does he have? How many crayons does he have? Thoughts Dotting: As can be seen from the figure, there are 5 crayons in the first box, 6 crayons in the second box, and eight crayons in the third box. Because there are two boxes of crayons are small light, small light crayon either box 1 and box 2 may also be the first box and the third box, but also the second box and the third box. Add them together to get: Box 1 and Box 2: 5 + 6 = 11 Box 1 and Box 3: 5 + 8 = 13 Box 2 and Box 3: 6+ 8 = 14 (branch)
