Question

Help me please I forgot my notes at school

Answer 1

1/2 x 6 = 3
3 x 8 = 24
24/6 = 4
4 - 1 = 3

3 is your answer

hope this helps

Answer 2

Because of BIDMAS, we know to do the brackets first
so it would be 3 * 8 ÷ 6 - 1
Division and multiplication next, so 4 -1
Lastly, subtraction
3

I am not 100% sure this answer is right but this is system I was taught
Hope it helped
