  1. Adding, Subtracting, Multiplying, Dividing, Fractions Madam Zakiah Hassan 23 February 2012

  2. Adding • To add whole numbers, you unite two or more numbers called addends to make one number called sum, total, or amount. • Example 1362 + 5913 7275

  3. Subtracting • Is opposite of addition • It takes one number away from another number. • The top (largest) is minuend. • The bottom (small) is subtrahend. • Example 4327 (minuend) • 1340 (subtrahend) 2987

  4. Multiplying • Sometimes it is shortcut to addition • The top number ( no we want to multiply) is multiplicand. • The bottom number ( number doing the multiplying) is the multiplier. • The final number (answer) is the product. • The number between the multiplier and the product are partial numbers. • Example 418 X 52

  5. Division • Reverse of multiplication & time saving shortcut related to subtraction. • Division ask how many times one number (divisor) is contained in another number (dividend). • The answer (result) is the quotient • Example

  6. Fractions • Explain the parts of whole numbers called fractions • Express Numerator, top of fraction Denominated - bottom of the fraction

  7. Fractions • Types • Proper fractions / simply fractions • Improper fractions • Mixed fractions

  8. Fractions • Adding • Subtracting • Multiplying • Dividing • Fractions maybe in figure or in term of problem solving.

  9. Rounding decimals • Decimal point is the center of the decimal numbering system. • Why  if you moves a digit to the left of the decimal point by places (ones, tens, and so on) you increase its value 10 times for each place. • Why  if you move a digit to the right of the decimal point by place ( tenth, hundredths, and so on), you decrease its value 10 times for each place.

  10. Rounding decimals • Example • Round to nearest dollar : $166.39  $166 • Round to nearest cent : 1,196.885  1,196.89 • Round to nearest hundredth : 38.563  38.56 • Round to nearest thousandth : 1,432.9981 -> 1,432.998
