Understanding Expressions in Wolframalpha

The video tutorial explores the evaluation of three mathematical expressions using Wolframalpha, with variables x and y set to 2 and 3, respectively. The instructor highlights a surprising outcome when Wolframalpha interprets one of the expressions differently than expected. The video emphasizes the importance of understanding how different calculators may interpret expressions, leading to varying results.

What values were assigned to x and y in the expressions entered into Wolframalpha?

• x = 4, y = 1

• x = 1, y = 4

• x = 2, y = 3

• x = 3, y = 2

What is the result of the first expression, 6 divided by the product of x and y, when x equals 2 and y equals 3?

• 2

• 1

• 0

• 3

How did Wolframalpha interpret the third expression, 6 divided by x times y?

• As 6 divided by x plus y

• As 6 divided by the product of x and y

• As 6x divided by y

• As 6y divided by x

What was the surprising outcome regarding the middle expression?

• It was interpreted as 6 divided by x plus y

• It was interpreted as 6 divided by the product of x and y

• It was interpreted as 6x divided by y

• It was interpreted as 6y divided by x

Is the interpretation of the middle expression consistent across all calculators?

• Yes, all calculators interpret it the same way

• Yes, but only for specific values of x and y

• No, it varies between different calculators

• No, only Wolframalpha interprets it this way
