## School Mathematics Competition

From 2006 till 2021 I was responsible for the Junior Division (years 7 and 8) of
The University of
Melbourne School Mathematics Competition.

The last competition for which I wrote the questions was held on the fifth of May, 2021.

Although I have now handed over my duties to Peter McNamara at the University of Melbourne, you will hopefully still be interested in participating in the 2022 competition.

To test you skills, try to compute the sum (no calculators allowed!)

1−2+3−4+···+97−98+99

Possible
answers are: 0,
1, 49, 50,
51, None of these.

Got a taste for it?

Then you may want to try the questions from
2009,
2010,
2011,
2012,
2013,
2014,
2015,
2016,
2017,
2018,
2019,
2020
or

Good luck.
