1) The document presents a math lesson where students are given sets of 3 digits and a result and must determine the signs needed to make the equations true.
2) Examples are given such as 2 + 2 + 2 = 6 and students are asked to solve additional problems.
3) The teacher provides hints and solutions to problems the students could not solve, and concludes the lesson by acknowledging the difficulty of factorials.
2. The goal of this lesson is solving maths
problems by applying what you
learned at school. (If you still
remember it)
3. I give you 3 digits and a result and you must put
all the signs necessary to restore the equality.
I give you an example. The remainder you solve
by yourself.
2 + 2 + 2 = 6
Easy! Isn't this? It is the same for the remainder.
5. What, did You solve some? … Not, N°2 : it was
the example, which I showed you presently .
¿ Another? Ah… N°6. Very difficult !!!
6 + 6 - 6 = 6
EINSTEIN!!!!!
6. ¿And the others? ? Do you want assistance?
Ah, not, I forgot you are intelligent.
I think that you solved the 3th ,
Perhaps the 5 th. With a little chance the 7th .
3 x 3 - 3 = 6
5 / 5 + 5 = 6
-7 / 7 + 7 = 6
Still not? Ok. We are here for that! - (7/7) = -1.
And thus 7 - 1 = 6
7. Now let we see those which are a little more complicated.
The 4th.
4 + 4 + 4 = 6
The 9th.
9 x 9 - 9 = 6
The 8th.
3 3 3
8+ 8+ 8 = 6
No Good ? Ahhh!!! That’s another thing!.
thing
8. On this, I finish today’s class
Ah, not… It’s ;true… It remains to solve the first one.
1+1+1 = 3 3x2x1 = Dunce’s cap!
1 + 1+ 1 ! = 6
Well I give you a track, but I must acknowledge this one
is muscular...
No ? Still not? You are not gifted in Maths, eh!!
FACTORIAL: the factorial of a number is obtained
by multiplying all the formers up to 1.
It is symbolised by the exclamation point.
