LO: to know the order in which operations must take place

I know what Bidmas means and can use it confidently.

I can use Bidmas with the information given, some of the time.

I don’t know the order at all or what it means.A

A challenge!

• Can you use the BIDMAS operations to make this statement correct?

• 1 2 3 4 5 6 7 8 9 = 100

• 1+2+3+4+56-7+8+9 =76
