Question

5. Higher Order Thinking Write two

Answer 1

Answer:

Here we have a math thinking case.

Usually when we add two numbers, we try to deconstruct the numbers in such a way that the sum is easier. One thing that we always try to do, is to make a 10.

For example, in;

4 + 9

We know that 9 = 6 + 3

Then we can write:

4 + (6 + 3)

And re do the sum as:

(4 + 6) + 3

10 + 3 = 13

Now, we want to apply the same principle, but this time we don't want to make a 10.

We also can, for example, make a 5, like in:

2 + 13

We know that 2 + 3 = 5

then:

2 + 13 = 2 + (10 + 3) = 2 + 3 + 10 = 5 + 10 = 15

Other similar example:

2 + 7

We know that we can rewrite 7 as 3 + 4

Then:

2 + (7) = 2 + (3 + 4) = 2 + 3 + 4 = 5 + 4 = 9

This is not exactly easier, but in some cases can be useful.
