6. If \( 16+1=17 \), does \( (16+1)-1=17-2 ? \)

"315. \( \left[\left(\frac{1}{2}-\frac{3}{8}-\frac{1}{16}\right)+\left(\frac{5}{3}+\frac{1}{4}-\frac{3}{2}\right):\left(\frac{3}{4}+3\right)\right] \times\left(\frac{8}{5}+8\right) \)

Do You Know How? in 5 and 6 , answer yes or no and explain why or why not. 5. If \( 23+37=60 \), does \( 23+37+9=60+9 \) ?

Write the number \( 3.7 \times 10^{-6} \) in standard form

\( \equiv \) 315. \( \left[\left(\frac{1}{2}-\frac{3}{8}-\frac{1}{16}\right)+\left(\frac{5}{3}+\frac{1}{4}-\frac{3}{2}\right):\left(\frac{3}{4}+3\right)\right] \times\left(\frac{8}{5}+8\right) \)
