Johnny is picking up the toys on the floor of his room.  He'd dumped a lego boxed set with 500 pieces on the floor, and another one that had 3 times more pieces than the 500 piece one, and another one that had 1/4 the number of pieces.  How many blocks does Johnny pick up if he picks up all the legos?
The first set had 500 pieces, and the second set had 3 times as many as the first set, so the second set has 500*3=
<gadget id="calculator">500*3</gadget>
<output>1_500</output>
1500 pieces.
The third set had one-quarter of the 500 pieces, so that means it had 500*.25= 
<gadget id="calculator">500*.25</gadget>
<output>125</output>
125 pieces.
In total, that means Johnny picked up 500 + 1500+ 125= 
<gadget id="calculator">500+1500+125</gadget>
<output>2_125</output>
2125 blocks.
