# A message from Patrick- 6th May 2020

Hello there!

Today I am going to put a number of maths puzzles here and you can all answer in the comments. Unfortunately, no gave there own one yesterday! I will put the challenges you make on this blog as long as you send them to me. Otherwise, I am happy to make my own (they are very fun to make).

I am thinking of a number:

• It is a three digit number
• It is less than the product of 8 and 25 (8×25)
• It is a square number (eg. 2×2=4, 4×4=16, 9×9=81, 15×15=225…)
• The factors of this number are prime numbers themselves (please comment what the definition of a primer number is)
• All three of its digits add up to more than 5

That one is very difficult. To make it even more challenging- YOU ONLY GET TWO GUESSES so you should check your answers and make sure it is right before you post in the comments!

Also:

How many triangles can you see?

You get as many guesses as you want for this one but I will only answer ‘correct’ or ‘incorrect’. No hints!

If you have any questions then as always please comment below or email me! I can give feedback on the writing competition plans or writing in general and I would love to see any extra work you have been doing so please send them as well!

Speak soon,

Patrick
