This sheet presumes making number into 10 helps make adding easier

2.  8 + 5 =

    10 +  3 = 13  we get 3 by taking 2 from 5 and giving it to the 8 to get 10


3.  8 + 6 =

     10 + 4  = 14     take 2 from 6 to give to 8 to make 10


I suspect the purpose of this is to promote mental math

Answer:

I'm going to explain this by doing number 2.

Step-by-step explanation:

Okay, so 8 is 2 away from 10. So we subtract 2 from 5, leaving 3. We add the 2 to the 8, making 10. Now, we add the other 3. 10+3=13. 8+5=13.

Are these correct? If not please help me write the correct answer.​
Keith_Richards [23]

Answer:

Mostly correct

For Q3, you are doing great, you remembered that negative numbers can happen if the exponent is an odd number.

For Q4, I think you were confused with the fractions,

4(i)

(\frac{2}{3} )^{4} = (\frac{2^{4}}{3^{4}}) = (\frac{16}{81}) =0.198

4(ii) is also wrong but I'll let you try to fix it yourself following what I given you for 4(i). You should get 1/64

Hope this helps!
