Translating multiplication using times, 17 times a number

The video tutorial explains the use of multiplication when dealing with 'times' in math problems. It introduces the concept of using a variable to represent an unknown number and demonstrates how to write algebraic expressions without needing to show the multiplication symbol explicitly. The example used is 17 times a number, represented as 17A.

Which mathematical operation is primarily used when dealing with times?

• Division

• Multiplication

• Subtraction

• Addition

What is the purpose of introducing a variable in a multiplication problem?

• To eliminate the need for numbers

• To simplify the equation

• To represent an unknown number

• To add complexity

If 'a' is a variable representing a number, how would you express 17 times this number in algebraic form?

• 17 * a

• 17 / a

• 17 - a

• 17 + a

Why is it unnecessary to use the multiplication symbol when writing 17 times a variable?

• It is not allowed in algebra

• It is only used in division

• It is too complex to write

• It is implied in algebraic expressions

What does the expression 17A represent?

• 17 divided by a

• 17 plus a

• 17 minus a

• 17 times a
