The Mysteries of Math: Evaluate The Expression. 4! • 3! 12 30 144 5,040

Have you ever encountered a mathematical expression that piqued your curiosity? Perhaps a curious assortment of numbers punctuated by an unfamiliar symbol – the factorial! Fear not, intrepid explorer of the numerical realm, for we are here to embark on a journey of discovery, unraveling evaluate the expression. 4! • 3! 12 30 144 5,040! and ultimately reaching the promised land of 144.

But before we delve into the heart of the equation, let’s arm ourselves with the necessary tools. Today’s expedition will necessitate a firm grasp of factorials. These mathematical marvels represent the product of all positive integers less than or equal to a given number.

For instance, 4! (read as “four factorial”) signifies 4 x 3 x 2 x 1. Likewise, 3! (three factorial) translates to 3 x 2 x 1.

Now, equipped with this newfound knowledge, let’s dissect the expression at hand: 4! • 3!

Here, the dot (·) symbolizes multiplication. Therefore, we are tasked with calculating 4! and 3! independently, and subsequently multiplying the results.

Scaling the Peak of 4!

Our first ascent takes us to the summit of 4!. Recall that 4! represents 4 x 3 x 2 x 1. With a resolute spirit, we embark on this multiplicative climb:

  1. 4 x 3 = 12
  2. 12 x 2 = 24

Having conquered these initial steps, we arrive at the triumphant peak of 24, which signifies the value of 4!.

Conquering the Plateau of 3!

Our next leg of the journey leads us to the plateau of 3!. Here, we must compute 3 x 2 x 1. With practiced ease, we navigate this familiar terrain:

  1. 3 x 2 = 6

Reaching the plateau, we discover the value of 3! to be 6.

The Bridge to 144: The Power of Multiplication

Now comes the moment of truth. We have scaled the mountains of 4! and 3!, and it’s time to bridge the gap between them using the mighty tool of multiplication. Remember, the dot (·) signifies multiplication in our expression.

Therefore, we calculate:

24 (value of 4!) x 6 (value of 3!) = 144

Huzzah! Through the combined might of factorials and multiplication, we have successfully reached the promised land – 144!

A Broader Perspective: Unveiling the Elegance of Factorials

Factorials hold immense significance in various branches of mathematics, including combinatorics, probability, and even calculus. They play a crucial role in counting arrangements, calculating probabilities, and exploring complex mathematical concepts.

For instance, imagine you have a group of 4 friends and want to determine how many different ways you can arrange them in a line. Factorials come to the rescue! The number of arrangements, known as permutations, can be calculated using 4!, which we now know equals 24.
