Solve 7×3-7×0= ? in less than a minute

As the popular expression suggests, “Mathematics is a universal language”.

This statement is based on the fact that no matter your origin or your culture, mathematical principles remain constant throughout the world.

Thus, whether it is a simple addition or a complex equation, mathematics is a field of study that has the power to unite the most diverse minds.

We’re going to test your understanding of this universal language by giving you a simple but potentially misleading math problem: 7×3-7×0.

Understand the basics

Before embarking on solving our puzzle, it is essential to understand the basic principles that govern mathematical operations.

Multiplication, represented by the symbol “×”, is the operation of adding a number to itself a certain number of times. For example, 7×3 simply means that you add 7 to itself 3 times, which is 21.

Subtraction, represented by the symbol “-“, is an operation that consists of removing one number from another. For example, if you have 21 and you subtract 7, you end up with 14.

Finally, multiplication by zero is a special rule in mathematics. No matter what number you multiply by zero, the result will always be zero. So 7×0 equals zero.

Apply order of operations

Once you have understood these basic principles, the next step is to correctly apply the order of operations, often referred to by the acronym BIDMAS or PEMDAS, which stands for: Parentheses, Exponents (or Indices), Division and Multiplication (of left to right), Addition and Subtraction (left to right).

  • First, resolve any operations in parentheses.
  • Then perform all exponent operations.
  • Then perform division and multiplication in order from left to right.
  • And finally, perform addition and subtraction in order from left to right.

Potential Pitfalls

Despite its apparent simplicity, this problem can pose a few pitfalls.

The most common is not following the correct order of operations. For example, if you perform subtraction before multiplication, you get an incorrect result.

Another common pitfall is forgetting the rule of multiplying by zero. Remember, no matter what number you multiply by zero, the result will always be zero.

As you can see, a simple equation like 7×3-7×0 can be a great way to test your understanding of basic math principles and the order of operations. It also demonstrates the importance of rigor and attention to detail in mathematics.

Solve 7×3-7×0

Now that you are equipped with the basic principles and the order of operations, you are ready to solve our equation: 7×3-7×0.

  • Start by doing the multiplications. 7×3 gives 21 and 7×0 gives 0.
  • Then subtract the result of the second multiplication from the result of the first. It gives 21-0.
  • Finally, perform the subtraction to get the final result: 21.

Practice and hone your skills

The best way to improve your math skill – whether it’s addition, subtraction, multiplication, division or beyond – is regular, repeated practice.

This not only strengthens your understanding of the concepts, but also increases your calculation speed and your self-confidence.

  • Solve a variety of math problems to strengthen your understanding of the concepts.
  • Practice regularly to increase your calculation speed.
  • Test yourself by solving complex equations to boost your self-confidence.

Use learning aids

In addition to regular practice, using learning aids can be extremely beneficial in improving your math skills.

There are a multitude of resources available, ranging from traditional text books to interactive mobile apps.

  • Explore text books and manuals for in-depth understanding of concepts.
  • Use mobile apps for interactive and fun learning.
  • See online tutorials for a visual explanation of concepts.

Remember that learning mathematics, like any other area of ​​knowledge, is a continuous process that requires time, patience and practice. So feel free to explore, learn and grow at your own pace.

In summary, the 7×3-7×0 math problem is a great example illustrating the importance of understanding the basic principles of math and the correct order of operations. With regular practice and the use of learning tools, you can not only successfully solve this problem, but also improve your math skills in general. So keep practicing, learning and taking on new challenges. And remember, every problem is an opportunity to learn and grow.
