Chelsea

I need help on question 16

Mr Warbrick

9:44

Okay, let's work through it together.

What's C going to be?

Chelsea

9:45

Mr Warbrick

9:45

Good, A is going to be?

Kacie

9:45

Can I have help on question 8

Mr Warbrick

9:45

Of course, give me 1 second while I help Chelsea, then we'll do 8 :)

Chelsea

9:45

Mr Warbrick

9:46

Good! So the 3 is actually 13, so we need to carry that 10 over to the next column

Mr Warbrick

9:46

So 8 + B + 1 = 0 so B must be?

Chelsea

9:47

Mr Warbrick

9:47

Excellent, so the 0 is actually 10. So carry that over. 6 + 1 + 1 = D

Then you have the value of all 4

Kacie

Mr Warbrick

Q8 Kacie - the easiest thing to do is to write 18 as 18.0 then all your digits line up correctly for the addition.

Chelsea

9:48

Is it 8

Mr Warbrick

9:48

Yes!

I need help on Q16

Mr Warbrick

9:50

If you scroll up slightly, you'll see the work me and Chelsea just did to help you find the answer!
There's even a picture of the question there so you should see where that is :)

Charlotte

9:50

Do we do the subtraction one when you finish the adding.

Mr Warbrick

9:50

Yes please.

Kacie

9:50

Mr war brick is the answer 103.4

Mr Warbrick

9:51

Mr Warbrick

9:51

It sounds right!

Olivia

im stuck on 15

Mr Warbrick

9:54

Okay, let's go through it together.

9:55

D is easy to work out, it must be 1

B is a little trickier. What do I take 8 from to get 6?

Lewis S

9:55

Mr Warbrick

9:55

Good, so B must be 4. But that changes the 8 in the ones column to a 7

9:56

So 7 - C = 3. What is C?

Lewis S

9:56

Mr Warbrick

9:56

Good. A is easy to work out. A - 1 = 1

Then you have all 4 digits
