Do You Know Much About Solving Inequalities?
Do you know much about solving inequalities? We can often solve inequalities by adding (or subtracting) a number from both sides (just as in Introduction to Algebra).

Inequality tells us about the relative size of how many values?
- A.
One
- B.
Two
- C.
Three
- D.
Four
Correct Answer
B. TwoExplanation
Inequality tells us about the relative size of two values. It compares two values and determines if one is greater than, less than, or equal to the other. It helps us understand the relationship between two quantities and is often represented using symbols such as < (less than), > (greater than), or = (equal to). By using inequality, we can compare and analyze the magnitudes of two different values.Rate this question:

Inequalities in taught under ....
- A.
Maths
- B.
Literature
- C.
Biology
- D.
Music
Correct Answer
A. MathsExplanation
Inequalities are taught under maths because they involve comparing two values or expressions using symbols such as , ≤, and ≥. In mathematics, inequalities are used to represent relationships between numbers and to solve problems involving ranges, intervals, and inequalities. This topic is not typically covered in literature, biology, or music, as it is more closely related to numerical reasoning and mathematical concepts.Rate this question:

- D.
+
Correct Answer
B. ≥Explanation
The greater than or equal to symbol, represented as "≥", is used to compare two values. It indicates that the value on the left side is either greater than or equal to the value on the right side. This symbol is commonly used in mathematics and programming to express relationships between numbers or variables.Rate this question:

≤
- B.
=
- C.
≥
- D.
+
Correct Answer
A. ≤Explanation
The symbol ≤ represents "less than or equal to." It is used to compare two values, indicating that the first value is either less than or equal to the second value. This symbol is commonly used in mathematics and inequalities to express relationships between numbers.Rate this question:

Who is not a mathematician among them?
- A.
Albert Einstein
- B.
Isaac Newton
- C.
Pythagoras
- D.
Hulk Hogan
Correct Answer
D. Hulk HoganExplanation
Hulk Hogan is not a mathematician because he is a professional wrestler and entertainer, not known for any contributions or expertise in the field of mathematics. On the other hand, Albert Einstein, Isaac Newton, and Pythagoras are renowned mathematicians who have made significant contributions to the field.Rate this question:

You flip the inequality sign whenever you multiply or divide the inequality by a ....
- A.
Positive
- B.
Equal sign
- C.
None
- D.
Negative
Correct Answer
D. NegativeExplanation
When multiplying or dividing an inequality by a negative number, the direction of the inequality sign must be flipped. This is because multiplying or dividing by a negative number reverses the order of the numbers being compared. So, if we have an inequality such as "x > y" and we multiply or divide both sides by a negative number, the inequality becomes "x < y". Therefore, the correct answer is negative.Rate this question:
