Question

6 – 4(3 – 5) + 30 ÷ 5 I need helpn working this out!

Answer 1

Use BODMAS:
Brackets
Orders
Division
Multiplication
Addition
Subtraction

Answer 2

\(6 – 4(3 – 5) + 30 ÷ 5 \implies 6 – 4(–2) + 30 ÷ 5\) (Brackets).
No orders so now we do division.
\(6 – 4(–2) + 30 ÷ 5 \implies 6 – 4(–2) + 6\) (Division).

Can you continue from there @justdechea ?

Answer 3

@gabby16404
How did you get that? (It is not correct.)

Answer 4

PEMDAS is better
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

Answer 5

6 – 4(3 – 5) + 30 ÷ 5
6 – 4(–2) + 30 ÷ 5
6 – 4(−4) + 30 ÷ 5
6 + 16 + 30 ÷ 5
6 + 16 + 6
22 + 6 28
@Opcode is thisright?

Answer 6

No. Let me show you one more step.
We just did division according to BODMAS next is multiplication.
\[6–4(–2)+6\implies 6 - (-8) + 6\]
We know because of basic arithmetic that a negative and negative make positive.
So:
\[6 + 8 + 6\]

Answer 7

I under stand now @Opcode the (-2) comfused me a little

Answer 8

No problem let me explain that part some more though :-).

\[4(-2)\]
Really means:
\[4 \times (-2)\]
Which makes:
\[-8\]
And since we had:
\[6 - 4(-2)\]
It really means:
\[6 - -8\]
And a negative and negative make positive so:
6 + 8

Answer 9

thanks
