Tricky maths exam question baffles students and parents trying to work it out

If you think you're good at maths, you might reconsider that after you read this mind-boggling equation.

A maths quiz about crickets has baffled thousands of high school students and parents who can't work it out.

School kids in Australia were presented with a confusing section after changes were made to the "standard" maths exam.

The paper asked students to calculate the number of chirps expected in a 15-second interval when the temperature is 19 degrees.

But the question left many baffled, despite it being "within the scope of the syllabus".

So do you think you can get the right calculation?

A spokesperson for NSW Education Standards Authority told news.com.au: "NESA confirms that all questions asked within the Maths Standard 2 exam were within the scope of the syllabus.

"All HSC exam papers are designed to differentiate student achievement. NESA will monitor marking of the Maths Standard 2 paper very closely. Mathematics education is a priority for the NSW Government."

The question reads: "Calculate the number of chirps expected in a 15-second interval when the temperature is 19 degrees.

"Give you answer correct to the nearest whole number."

Many believed the issue with the paper was that both the standards maths exam and advanced had many of the same questions.

The spokesperson continued: "The Maths Advanced and Maths Standard 2 papers now include some common questions which are based on shared syllabus content.

"This year 23 marks were common to the two papers.

"The inclusion of common questions enables NESA to better understand student maths abilities across the different maths courses."
