Using number 7 only 4 times, signs of division, multiplication, addition, subtraction and brackets get all numbers from 0 to 10. For example: 7 + 7 - ( 7 + 7 ) = 0
Arrange brackets in this equation 4 · 12 + 18 ÷ 6 + 3 to get:
number 50;
the biggest possible number.
Between numbers 1, 2, 3, 4, 5, 6, 7, 8 and 9, written in this order, put signs of addition and multiplication such that the result will be 100. (You cannot use brackets. You cannot combine digits)
Make these equations correct by using mathematical operations:
Numbers 2, 4, 8, 16, 32, 64, 128, 256 and 512 arrange in the cells of the table 3x3 such that the multiplication of all number in rows, columns and diagonals is the same.
Solve this equation: T – W – O = T ÷ W ÷ O = 2 (different letters are different numbers).
Which number is 7 times more than its last digit.

Where do you hold your classes?
We hold our classes online or on-site on Saturdays at our branch in Pimlico Academy, London. You can find our timetable here.
What do you need to start learning online?
For lessons you only need a computer or phone with a microphone, camera and Internet access. Wherever you are - in London, Nottingham, New York or Bali - online lessons will be at hand.
When can I take the trial lesson?
You can get acquainted with the school at any time convenient for you. To do this, just leave a request and sign up for a lesson.
What should I expect from the trial lesson?
The trial lesson is a 30-minute online session designed to get a sense of how your child approaches mathematical thinking and problem solving. (In practice, it often runs a bit longer if the student is engaged!)
We typically explore a range of fun and challenging problems drawn from competitions. We adapt the difficulty based on how the student responds, aiming to make it both accessible and stimulating.
After the session, we’ll have a quick conversation with the parent to share observations and suggest a personalised path forward.
I can't attend class, what should I do?
It is OK, it happens! Students have the opportunity to cancel a lesson up to 8 hours before the scheduled time without loss of payment. So you can reschedule it for a convenient time, and the teacher will have the opportunity to
I don't have much free time, will I have time to study?
Learning can take place at your own pace. We will select a convenient schedule and at any time we will help you change the schedule, take a break or adjust the program.
How long is one lesson?
All classes last 1 hour.
