•
1 like•1,229 views
Multiplication is a quick form of addition and a shortcut for adding equal numbers. It involves multiplying a number by the ones place, tens place, and hundreds place of another number and then adding the partial products together to get the final product. When multiplying larger numbers, this process is done without regrouping the numbers.

Subtraction with regrouping
The document discusses regrouping or borrowing in subtraction. It explains that regrouping involves taking ten from one number to give to another when subtracting two numbers where the number being subtracted is larger than the number it is being subtracted from. Examples are provided to demonstrate regrouping, and an interactive game asks the reader to identify when regrouping is necessary in subtraction problems. The document concludes by recapping that regrouping is needed when the number being subtracted is larger than the number it is being subtracted from.
Subtraction without and with regrouping 3 4 digit numbers
Sean sold 342 boxes of cupcakes last week and 557 boxes this week. To find the increase in sales, we subtract last week's amount from this week's, giving 557 - 342 = 215. Another method is to write the numbers as 4986 - 2354 = 2632 to find the difference between them by arranging the digits in columns and subtracting. Subtraction allows regrouping of digits when the number in the top row is less than the number below it in a column.

Place value gr2
Place value is a system that determines the value of a digit in a number based on its position. Each position in a number has an associated place value, such as ones, tens, hundreds, and thousands. The value of the digit depends on which place value position it occupies. For example, in the number 5,728, the 8 is in the ones place and has a value of 8, the 2 is in the tens place and has a value of 20, the 7 is in the hundreds place and has a value of 700, and the 5 is in the thousands place and has a value of 5,000. Together these digit values make up the total value of the number.

Several word problems involving rates and distances are solved as examples using multiplication of mixed decimals.
Adding Decimals
The column method is used to add decimal numbers. First, the numbers are lined up with the decimal points aligned. Then each column is added separately, carrying numbers to the next column as needed. For the example of adding 3.77 and 4.28, the hundreds column is added first (7 + 8 = 15, writing the 5 and carrying the 1). Then the tens column is added (7 + 2 + 1 = 10, writing 0 and carrying 1). Finally, the ones column is added (3 + 4 + 1 = 8). The total is 8.05 + 1 = 8.08.
