Don't do it left to right, cancel them in pairs.      

With my fiercest, bravest transformer at the helm how can Camelot's great army not win!

Go forth and protect this magical land.

$$\left({\frac{\left({\mathtt{2.99}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{6}}}\right)}{{\mathtt{44.892}}}}\right){\mathtt{\,\small\textbf+\,}}{\mathtt{146.04}} = {\mathtt{66\,750.334\: \!751\: \!848\: \!881\: \!760\: \!7}}$$

Well the first three digits are 667 (the next one 5 is used for rounding if it is 5 or bigger the the third one goes up)  so now we have

668  but 668 is much smaller than 66 750  we can't have that. We need some zeros but they are not significant.

So the answer is 

66,800

I am glad that you read my wrap but a wrap is not a question.   It is usually just information 

Sorry the question makes no sense to me.   

(that is because there is an x and a y)

$$\\1,500.00 (1+.04)^5\\
=1500 (1.04)^5\\$$

just do it on the site calc on the home page

1500*(1.04)^5

|22| × (-6 + 5)

absolute value of 22 is 22

22*(-1)

=-22

Just divide both sides by minus 3 but remember that when you multiply or divide by a negative you have to swap the sign around.   

Haley - Honga want you to press the thumbs up on his answer.  That will give him points.  

(I'll give you some points Honga  )
