Using addition and subtraction when grocery shopping can really help you manage your money better. Here’s how to do it:

1. Budgeting

• Set a Total Budget: Decide how much money you want to spend. For example, if your weekly budget is $500, this is the most you want to use.

• Track Expenses: While you shop, keep a running total of how much you’re spending by adding up the prices of the items you want.

  For example, if you add up items that cost $320, you can see how much money you have left to spend:

  $500 -$320 = $180

  This means you have $180 still available to spend.

2. Identifying Discounts

• Use Addition for Discounts: If an item costs $40 and has a 20% discount, you can find out how much you save and what the new price will be.

  First, calculate the savings:

  $40 × 0.20 =$8

  Then, subtract this amount from the original price:

  $40 -$8 = $32

  You can use this method for other items to see how much you save in total.

3. Comparing Prices

• Calculate Each Option: When you see different brands or sizes of a product, add up the total prices to find the best deal.

  For example, if Brand A costs $15 for 1kg and Brand B costs$12 for 0.8kg, you need to figure out how much each one costs per kg:

  • Brand A: $15 for 1kg
  • Brand B:

  To find out the price per kg for Brand B, divide:

  $12 ÷ 0.8 =$15

  Now you can see that both brands have the same cost per kg. Choose the one that gives you the best value for your money.

Using addition and subtraction wisely can help you save money and make better choices while grocery shopping.
