$10-(\frac{1}{2})^4 \cdot 48$ is this your equation?

4. anonymous

yes

5. UsukiDoll

ok so order of operations is coming into play PEMDAS P is the parenthesis and E is the exponent... looks we got a 2 for 1 special solve $(\frac{1}{2})^4$ first the exponent is 4 which means write $\frac{1}{2}$ 4 times

6. anonymous

that is 2 wholes

7. UsukiDoll

$\frac{1}{2}\frac{1}{2}\frac{1}{2}\frac{1}{2}$ no we are doing multiplication

k

$\frac{1x1x1x1}{2x2x2x2}$ what's 1 x 1 x 1 x 1 what's 2 x 2 x 2 x 2

1 x 1 x 1 x 1=1 2 x 2 x 2 x 2=16

11. UsukiDoll

yup so our fraction is 1/16 $10-\frac{1}{16} \cdot 48$ now we have M D which is multiplication and division what is $\frac{1}{16} \cdot 48$

3?

13. UsukiDoll

very good :) now we just have 10-3 we don't have A (addition) so skip it We do have S (subtraction) 10 - 3 = ?
