Study Notes
- Keri and Val are baking cookies to fill customer orders.
- To add the columns, they follow the rules of carrying and regrouping to get the total number of cookies to be baked.
- Subtraction is the next operation. To subtract, line up the numbers by place value and borrow from the next place value if necessary.
- Val receives a call from a customer who wants to reduce her order of sugar cookies by 134.
- Val must subtract 134 from the original order of 524 to determine the new order.
- Multiplication is another operation. Val wants to know how many cookies they would need to cook daily to reach a certain number over a certain period.
- To multiply, take each place value and multiply it to every value in the other number, adding zeros as necessary and carrying values as needed.
- Division is the last operation. Val wants to know how many cookies each customer would receive if they sell 715 cookies for 126 days.
- In division, set up the problem with the dividend (715) and divisor (12), divide the divisor into each value of the dividend from left to right, and write the number of times it divides as the quotient.
- The remainder is the value that remains after all places have been divided.
- Val determines that each customer would receive 59 cookies, and they would have 7 cookies left over.
