It should be 48-(-40)=88

It should be (-40) and not 40.

It should be 48-(-40) =48+40 =88

-48+40= 88

The correct working should be :(-16)x(-3)-(-8)x5=48-(-40)=88

its suppose to be48+8x5=88

(-16)x(-3)-(-8)x5=48-(-40)=48+40=88The negative sign for '(-8)' disappeared.

(-8)x5= to -40 not 40.so the equation should be: 48 - (-40) = 88

It should be negative 40.(-16)x(-3)-(-8)x5=48-(-40)=88

it should be:(-16)*(-3)-(-8)*5=48-(-40)=88and not:(-16)*(-3)-(-8)*5=48-40=8

The second part of the equation. (-8)*5 is equal to (-40). When you remove the brackets the negative and the negative while turn into positive. Thus it becomes 48+40=88

(-46) x (-3) - (-8) x 5=48-(-40)=48+40=88

The working is wrong.Instead of ...(-16)x(-3)-(-8)x5=48-40=8(Ans)It should be...(-16)x(-3)-(-8)x5=48-(-40)=88(Ans)

For the second number sentence, it should be 48+40 instead of 48-40. Thus, the answer should be 88.

(16) x (-3) - (-8) x 5= 48- (-40)= 88 ( Answer )It is 48 subtract (-8) x 5 and not 48 subtract 8 x 5Therefore it is 48- (-40) instead of 48-40 and the answer is 88 instead of 8.-Christopher Nah

The equation should be expressed like this:48-(-40)=88 , and not 48-40=8

(-16)x(-3)-(-8)x5=48 - -40=88

It is wrong as (-8) multiplied by 5 = (-40).Then 48-(-40) as negative and negative equals to 48+40.So the answer is 88.

It should be (-16)x(-3)-(-8)x5=48+8x5=48+40=88

it is:(-16)x(-3)-(-8)x5=48-(-40)=88instead of:(-16)x(-3)-(-8)x5=8=48-40

The answer is wrong as (-8)x5 is -40 so if you subtract 48-(-40)equals 88.

The correct answer is:(-16)x(-3)-(-8)x5=48--40=48+40=88

(-16)x(-3)-(-8)x5=48+40=88(Ans)

Class S1-02Well done... all of you are able to identify what's wrong with the working.Notice that a few of you put down, as part of your working like 48--40 or 48 - -40Please remember, when we have 2 signs side by side, they have to be separated by the bracket ().Cheers!Ms Loh

ReplyDeleteIt should be (-40) and not 40.

ReplyDeleteIt should be 48-(-40)

ReplyDelete=48+40

=88

-48+40

ReplyDelete= 88

The correct working should be :

ReplyDelete(-16)x(-3)-(-8)x5

=48-(-40)

=88

its suppose to be

ReplyDelete48+8x5

=88

(-16)x(-3)-(-8)x5

ReplyDelete=48-(-40)

=48+40

=88

The negative sign for '(-8)' disappeared.

(-8)x5= to -40 not 40.

ReplyDeleteso the equation should be: 48 - (-40) = 88

It should be negative 40.

ReplyDelete(-16)x(-3)-(-8)x5

=48-(-40)

=88

it should be:

ReplyDelete(-16)*(-3)-(-8)*5

=48-(-40)

=88

and not:

(-16)*(-3)-(-8)*5

=48-40

=8

The second part of the equation. (-8)*5 is equal to (-40). When you remove the brackets the negative and the negative while turn into positive. Thus it becomes 48+40=88

ReplyDelete(-46) x (-3) - (-8) x 5

ReplyDelete=48-(-40)

=48+40

=88

The working is wrong.

ReplyDeleteInstead of ...

(-16)x(-3)-(-8)x5

=48-40

=8(Ans)

It should be...

(-16)x(-3)-(-8)x5

=48-(-40)

=88(Ans)

For the second number sentence, it should be 48+40 instead of 48-40. Thus, the answer should be 88.

ReplyDelete(16) x (-3) - (-8) x 5

ReplyDelete= 48- (-40)

= 88 ( Answer )

It is 48 subtract (-8) x 5 and not

48 subtract 8 x 5

Therefore it is 48- (-40) instead of 48-40 and the answer is 88 instead of 8.

-Christopher Nah

The equation should be expressed like this:

ReplyDelete48-(-40)=88 , and not 48-40=8

(-16)x(-3)-(-8)x5

ReplyDelete=48 - -40

=88

It is wrong as (-8) multiplied by 5 = (-40).Then 48-(-40) as negative and negative equals to 48+40.So the answer is 88.

ReplyDeleteIt should be

ReplyDelete(-16)x(-3)-(-8)x5

=48+8x5

=48+40

=88

it is:

ReplyDelete(-16)x(-3)-(-8)x5

=48-(-40)

=88

instead of:

(-16)x(-3)-(-8)x5

=8

=48-40

The answer is wrong as (-8)x5 is -40 so if you subtract 48-(-40)equals 88.

ReplyDeleteThe correct answer is:

ReplyDelete(-16)x(-3)-(-8)x5

=48--40

=48+40

=88

(-16)x(-3)-(-8)x5

ReplyDelete=48+40

=88(Ans)

ReplyDeleteWell done... all of you are able to identify what's wrong with the working.

Notice that a few of you put down, as part of your working like

48--40 or 48 - -40

Please remember, when we have 2 signs side by side, they have to be separated by the bracket ().

Cheers!
