Problem: Article: Circle pairs of 1s (digits) in the ones column. Remember, the ones column in binary is the far right column. For example, if adding 1010 + 1111 + 1011 + 1110, you should circle 1 pair of 1s. For each pair of 1s, carry a 1 into the twos column. If there is only one 1, or if there is one 1 left over after circling pairs of 1s, then write a 1 in the answer’s ones place. If there are no 1s left over, place a 0 in the answer’s ones place. For example, since you circled one pair of 1s, you would carry a 1 into the twos column, and drop a 0 in the answer’s ones place. Don’t forget to include any digits you carried over from the ones column. For example, if adding 1010 + 1111 + 1011 + 1110, you should circle 2 pairs of 1s, and have one 1 left over. For each pair of 1s, carry a 1 into the fours column and drop a 0 into the answer’s twos place. If there is only one 1, or if there is a 1 left over after circling pairs of 1s, then place a 1 into the answer’s twos place. If there are no 1s left over, place a 0 in the answer’s ones place. For example, since you circled 2 pairs of 1s and had one 1 leftover, you would carry a 1 into the fours column twice, and drop a 1 in the answer’s twos place. Don’t forget to include any digits you carried over from the twos column. For example, if adding 1010 + 1111 + 1011 + 1110, you should circle 2 pairs of 1s, since you carried 1 over twice from the twos column. Carry over a 1 into the eights column for each pair of 1s. Don’t forget to put a 1 in the fours place if you have one 1 left over, or a 0 in the fours place if you have no 1s left over. For example, since you circled 2 pairs of 1s with none left over, you would carry a 1 into the eights column twice, and place a 0 in the answer’s fours column. Don’t forget to carry a 1 into the next column for each circled pair, to place a 1 in the answer if there is a 1 left over, and to place a 0 in the answer if only zeros remain in the column. For example, if adding 1010 + 1111 + 1011 + 1110, for the eights place you should circle 3 pairs of 1s, since you carried 1 over twice from the fours column. So you would place a 0 in the eights place of your answer and carry three 1s into the sixteens column. In the sixteens column you have one pair of 1s with one 1 left over, so you would place a 1 in the sixteens place of your answer, and a 1 in the thirty-twos column of your answer. So 1010 + 1111 + 1011 + 1110 = 110010. There are a number of binary calculators online that will calculate the sum of binary numbers.
Summary: Set up the problem vertically. Interpret the ones column. Circle pairs of 1s in the twos column. Interpret the twos column. Circle pairs of 1s in the fours column. Interpret the fours column. Continue circling pairs of 1s for each place value. Check your answer.

Problem: Article: Place the banana leaves into the steamer to provide a barrier between the boiling water and the tamales. Make sure that the entire base of the steamer is covered with the leaves. If you don’t have any banana leaves, use strips of corn husks instead. Spread the tamales across the base of the steamer with the open side facing up. If you have lots of tamales, stack a second layer over the bottom layer. Spread the tamales evenly across the steamer so that they cook at a similar speed. Don’t steam more than 2 layers of tamales at a time as this makes it difficult for the steam to reach the middle layers. Place the steamer rack into the steamer and place the lid on. Set a timer to help remind you to check the tamales. If the water in the steamer stops boiling, simply turn the heat up. Check the steamer occasionally to ensure that there is still plenty of water boiling. If necessary, add more water. Turn the heat off but leave the tamales in the steamer with the lid on. This helps the tamales to soften further and brings out the flavours. Set a timer to signal when 30 minutes is up. Transfer the tamales to a platter with metal tongs. Eat the tamales by themselves or with a side. Corn chips, guacamole, beans, and salsa are delicious Mexican side options. The tamales will be really hot. If you prefer the tamales warm, wait five minutes for them to cool slightly.
Summary: Line the steamer with a single layer of banana leaves. Place the tamales into the steamer. Leave the tamales to steam for 1 hour and 20 minutes. Leave the tamales to rest for 30 minutes in the covered steamer. Enjoy the tamales warm with your favourite Mexican sides.

Problem: Article: If you plan to live stream voice, then a microphone is necessary. Most modern laptops have an internal microphone, but desktops will need to connect one externally.

Audio mixers or speakers are some examples of external sources that can be used. You can select “Reload devices…” from the menu if you have a device connected but do not see it listed. This button will either be labeled “Select Source” or display the name or the microphone currently selected. The menu will display all microphones available for use. You can select “No Input” from the menu or turn the channel off if you do not want to use microphone input. This is indicated by the gear icon in the upper left corner of the window. Here you can enter a name/category for your stream, toggle recording, or test mode.  A stream name/category will help other identify your stream on the mixlr website.
