Answer:
1) 120
2) 186
Step-by-step explanation:
so you need to use BIDMAS (if your from the UK, I think its called PEMDAS in the US but I'm not sure)
so first you need to work out what's inside the brackets/parentheses
7(18-6)+12(4-1) = 7(12) + 12(3)
then you need to do multiplication/division
7(16) +12(3) = 7x12 + 12x3 = 84 + 36
finally you do addition/subtraction
84+36 =120
just repeat the same process for question 2
26 + 8(126÷6) - 8 = 26 +8(21) - 8
= 26 + 8x21 - 8
= 26 + 168 - 8
= 186
