NASA’s STEM engagement account on Twitter celebrated the 50th-anniversary moon landing by posting an interesting puzzle.

Reaching the moon doesn't have to be that hard. Can you solve this math problem, adapted from NASA's own STEM Engagement program?

OK! So, now let’s get down to solving this puzzle. And we have two ways of going about it – a visual method; and a purely algebraic method. Let’s start with the visual one!

Method #1: Visual Method

Now, this image can be redrawn as (focus on row 2):

Further (focus on column 1):

Now on replacing Moon we get the following equation, and hence the value of the Moon

Moon (m) = 20

Further (focus on column 2):

Thus, all of them were born in 1930.

And now let’s do it the algebra way!

Method #2: Algebraic Method

Let’s assume the values are:

a is the value of the astronaut

m is the value of the moon

r is the value of the rocket

e is the value of the satellite

Now, let’s form the equation using the puzzle information:

a + m = 45

r x e = 14

a + r = 32

m x e = 40

Using the last equation:

m = 40/e

Putting this into the first equation:

a + 40/e = 45

a = 45-(40/e)

Putting this in the third equation:

45-(40/e) + r = 32

r = 32 – [ 45-(40/e)]

Putting this in the third equation:

{32 – [ 45-(40/e)]} x e = 14

32e – 45e + 40 = 14

45e – 32e = 40-14

13e = 26

e = 2

Therefore,

m = 40/e = 40/2 = 20

a = 45 – m = 45 – 20 = 25

Therefore,

(a x e) – m = (25 x 2) – 20 = 50-20 = 30

So, 1930 is the answer!

Frequently Asked Questions (FAQs)

1. What is STEM Education?

STEM is a curriculum based on the idea of educating students in four specific disciplines — science, technology, engineering and mathematics — in an interdisciplinary and applied approach.

Rather than teach the four disciplines as separate and discrete subjects, STEM integrates them into a cohesive learning paradigm based on real-world applications.

2. What is NASA's STEM Engagement Program?

NASA STEM Engagement strives to increase K-12 involvement in NASA projects, enhance higher education, support underrepresented communities, strengthen online education, and boost NASA's contribution to informal education.

The intended outcome is a generation prepared to code, calculate, design, and discover its way to a new era of world innovation.
