M33: What are the missing numbers?
The same functions are used in each line. Can be used to develop algebraic thinking, for example, the numbers in the triangles are 4 times the numbers in the squares.

2. Random add and subtract
3. Fixed multiply and divide
4. Fixed multiply and add or subtract eg x 2 + 1
5. Random multiply and add or subtract
6. A variety of operations, eg rounding
