Why can’t you divide a certain number by zero?
The complete phrasing of the question: Why can’t you divide a certain number by zero? Supposedly, the meaning of dividing by zero is that you do not divide the number (you “divide” it to 0 sets…) and so the result should be the same as the number divided?

Does the rule of positive numbers, in which dividing 10 by an increasingly smaller number increases the product, also works when we divide 10 by a negative number? Choose the correct response.
No, the more you divide 10 by an increasingly smaller negative number, the result decreases.

The X axis represents the denominator (the dividing number).
The Y axis represents the quotient (the product of the division).
Based on the explanation, why does 10 divided by 0 tends towards infinity? Choose the correct answer.
When you divide by 0 there is no way of knowing the product, and therefore an unknown product tends towards infinity.

It is not clear how the exercise is performed, and it is custom to mark unknown answers as infinity.

When you divide 10 by a number that slowly tends towards zero, you get an enormous product, and therefore it tends towards infinity.
Well Done! Partial Correct Answer Correct Answer Incorrect Answer
When you divide 10 by a number that slowly tends towards zero, the product becomes very small, and therefore something that is almost zero tends towards infinity.

Draw a line between the number at column A to its multiplicative inverse in column B
The creation of Complex Numbers, at the early 16th century, is attributed to Girolamo Cardano that used them to solve cubic equations. These numbers were explicitly defined by Rafael Bombelli in 1527. During that time, these numbers were considered unreal. Mathematician found it hard to grasp the new concept, as evident by the name they attributed to these numbers.
In summary, in the world that we employ of normal numbers, can you divide by zero? If so, what is the product? Choose the correct answer.
You can divide by zero, and the quotient is 0.
