ROUND TO THE NEAREST HUNDRED

• The TARGET or FOCUS number is the 2 (in the HUNDREDS place)

• Look at the digit to the RIGHT of the TARGET number (it's a 5 so the TARGET NUMBER INCREASES BY 1)

• Keep the digits to the LEFT of the target number the same. Change all the digits to the RIGHT of the target number to zero
