• How do you remember which axis goes first? Is it Y axis or X axis?
• Chloe you know because the X axis comes first and the Y axis comes next like here's an example (9,8)so the 9 is the X axis and the 8 is the Y axis so there you go :3 :>
• At 0.:25 what does "blocks" mean? (Serious question)
• blocks mean streets in the example that Sal uses in the video
• assume you have 5.7 * 14.73. First number has decimal after 1st digit, second number has after 2 digits.
You can directly multiply without seeing decimal and put decimal after third number (1+2) from left to the answer. You may get proof if you write it as
(57/10) * (1473/100) = (57*1473) / (10*100) = 83961/1000 = 83.961
