Week 6&7

Hi,

Sorry I didn't do my week 6 blog post so I am joining it in with week 7's.

In maths I learnt about integers. Integers are things like -7x7=    12÷-3    5+-6     -7-8

Adding Integers:

-12+8=

Subtract the smaller number.

-12-8=-4

Because the larger number (-12) is a negative number the answer is negative.

Subtracting Integers:

11-(-7)=

Convert the smaller number to it's opposite sign. (-7 becomes positive 7)

11-7=

Now add the numbers.

11+7=18

Multiplying Integers:

If the signs are the same (-12 x -2 or 16 ÷ 4) the answer is positive (-12 x -2= 24 or 16 ÷ 4 =4).

If the signs are different (8 x -7 or -24 ÷ 6) the answer is negative (8 x -7 =-56 or -24 ÷ 6= -4).

In writing and reading I have learnt things about the holocaust. On camp we are visiting the holocaust centre. We are going to write a report about the holocaust, so we have been reading about it.

I also learnt in maths about standard form.
