    The first slides deal with this.

Do you remember this?

And the next slide is a useful one, too!

Task 1.      Solve this and key in your answer in the next slide:

2x3​3​​

Solution:

    = 2 x 3 x 3 x 3 = 54

Task 2.    Do the same with:

1+2​4​​x5​2​​

=

Solution:

= 1 + 2 x 2 x 2 x 2 x 5 x 5 = 1+ 16 x 25 = 

    1 + 8 x 50 = 1 + 4 x 100 = 401

Wanna hear an old Indian proverb?

Watch the next slide!

Old Indian saying (as they say):

One Joke is more fun than 10 LessonUps from Mr. Hauwert.

That's a good reason for the following slide!

Homework time.

For example:

4 + 6 x 3 -4 =  4 + 12 - 4 = 16 - 4 = 12
