'It Was 2010!' printed from http://nrich.maths.org/
At the start of a new year teachers often like to use the number of that year.
Well I know that some teachers often use an idea like,
The pupils would get things like:
$16 \div 2$
$20 - 4 - 4 - 4$
$6 + 2$
So here's a challenge to make an answer of $2010$
You could try things like:
$$2000 + 10 \quad\quad 201 \times 10\quad\quad 500 + 1000 + 500 + 5 + 5$$
$$19^2 +25^2 + 32^2$$
Don't forget you might like to use calculators or computers!
See what different questions you can find and compare yours with others.
Perhaps you can make up one that is easy, one that is harder and one that is very hard.
Now that $2010$ has passed try the same for the year we have now!
