Maths Game using Playing Cards

This is a game I made up to teach my youngest son some maths principles. using basic playing cards

K = 13            Q = 12  J = 11 A = 1

♥ = add zero to both numbers

♠ = Multiply answer by 5

♣ = subtract instead of add

♦ = Double the numbers

♥ & ♥ = Add 2 zeros to both numbers e.g. 10 ♥ + J ♥ = 1000 + 1100

♥ & ♦ = Add 1 zero to each number then double them e.g. 5 ♥ + 10 ♦ 100 (50 x 2) + 200                 (100 x 2)

♥ & ♠ = Add a zero to each number, add them together and then multiply the answer by 5

♥ & ♣ = Add a zero to the numbers and take away e.g. 4 ♥ + K ♣ = 40 – 130 (can it be done? Play about moving the numbers around to see what works!

♠ & ♠ = Just multiply the answer by 5

♠ & ♦ = Double the numbers and multiply the answer by 5

♦ & ♦ = Double both numbers and double the answer too!

If you have 2 A’s together add 2 zeros and follow the other rules

e.g. A ♥ & A ♦ = 1,000 (don’t forget to add the zero as there’s a heart) + 1,000 – now double them both and add them together – 2,000 + 2,000 = 4,000

Can you make up new rules? Play around and have fun!
