UNDERSTAND MATH THRU ENGLISH 2

Group numbers using correct punctuation marks: In English, you’d instead use a comma to separate groups of numbers in threes. For example: 12,300 — “Twelve thousand, three hundred” 1,500,050 — “One million, five hundred thousand fifty” $4.99 — “Four dollars and ninety-nine cents” (note that you might also hear this read as “four ninety-nine”) $645.50 — “Six hundred forty-five dollars and fifty cents”

Read numbers between 1100 and 9999 with “hundred”: For example: • 1100 can be read as “eleven hundred,” rather than “one thousand, one hundred.” • 3200 can be read as “thirty-two hundred,” rather than “three thousand, two hundred.” • 4552 can be read as “forty-five hundred fifty-two,” rather than “four thousand, five hundred fifty-two.” • 8429 can be read as “eighty-four hundred twenty-nine,” rather than “eight thousand, four hundred twenty-nine.” You’ll sometimes hear this when Americans refer to the White House by its address, as “sixteen hundred Pennsylvania Avenue” (1600 Pennsylvania Avenue). Another example is the science-fiction series “The 4400,” which is read as, “The Forty-Four Hundred.”

Use singular number words for specific numbers: In English, when we say specific large numbers, words such as “thousand,” “hundred thousand,” “million,” “billion” and “trillion” always stay singular—even though what they’re describing, like “dollars” or “people,” are plural. So, you would say “five million dollars ($5,000,000)” but not “five millions dollars.” “Sixty thousand people (60,000 people)” is correct. “Sixty thousands people” is not. You’d only say “hundreds” or “thousands” or “millions” if you weren’t specifying a particular number. In other words, you can correctly say, “billions of people” or “trillions of dollars,” as long as you’re not including an exact figure. But, if you were to say an exact number—like “five billion people” or “eighteen trillion dollars”—you’d have to drop the “s.”
