Introduction to Inequality Symbols in Mathematics

The video tutorial introduces the concept of inequalities, explaining the difference between equations and inequalities. It covers the various inequality symbols, such as greater than, less than, and their combinations with equality. The tutorial uses examples to illustrate how these symbols are applied in mathematical expressions, emphasizing the importance of understanding which side of the inequality is larger. Special cases, such as when variables can be equal, are also discussed, providing a comprehensive overview of how inequalities are used in mathematics.

What is the primary difference between an equation and an inequality?

• An equation shows that two sides are equal, while an inequality shows they are not.

• An equation uses symbols like < and >, while an inequality uses =.

• An equation is used only in algebra, while an inequality is used only in geometry.

• An equation shows that two sides are not equal, while an inequality shows they are.

Which symbol represents 'greater than or equal to'?

• <=

• <

• >

• >=

Which inequality symbol is used to indicate that one value is less than another?

• >

• <

• =

• >=

If X is not less than Y, which of the following could be true?

• Both A and B

• X is equal to Y

• X is greater than Y

• X is less than Y

If 10 and 8 are compared, which inequality is correct?

• 10 < 8

• 10 <= 8

• 10 > 8

• 10 = 8

How would you represent that a number X is between 5 and 9?

• X > 5 > 9

• 5 > X > 9

• X < 5 < 9

• 5 < X < 9

What does the inequality -3 < A < 0 mean for integer values of A?

• A can be any negative number

• A can be -2 or -1

• A can be -3 or 0

• A can be -3, -2, -1, or 0
