Combine the numbers in order from hundreds place, tens place, and ones place.
The answer is:
Example Question #69 : Real Numbers
Subtract the numbers:
Borrow a one from the tens place to subtract the ones digits. The tens digit of 1093 is now eight.
We cannot borrow a one from the hundreds place to subtract eight with nine, so we will need to borrow a one from the thousands place instead. The thousands place of 1093 is now zero, and the hundreds place becomes a nine.
Subtract the tens places.
Subtract the hundreds places.
Combine the hundreds, tens, and ones digits.
The answer is:
Example Question #1 : How To Multiply Integers
Evaluate 5x + 3y when x = 7 and y = 9.
–66
62
–62
8
66
62
Plug in 7 for x and 5 for y, giving you 5(7) + 3(9). This is equal to 35 + 27, which equals 62.
5x + 3y
5(7) + 3(9)
35 + 27 = 62
