For each of the following expressions, show each step a student would folow to mentally perform the calculations in the whole numbers. For each step, identify the law, definition , axiom ec that was used to roduce that step.
345+641+255+359
It sounds like working with the ones column first, then going to the tens and hundreds column. Your text should help you with the second part of your question.
I hope this helps. Thanks for asking.
I DON'T CARE
To mentally perform the calculation for the expression 345 + 641 + 255 + 359, a student would typically follow the steps below:
Step 1: Add the first two numbers, 345 and 641.
- Law/Definition/Axiom used: Addition in whole numbers.
- Calculation: 345 + 641 = 986.
Step 2: Add the result from Step 1 to the next number, 255.
- Law/Definition/Axiom used: Addition in whole numbers.
- Calculation: 986 + 255 = 1,241.
Step 3: Add the result from Step 2 to the final number, 359.
- Law/Definition/Axiom used: Addition in whole numbers.
- Calculation: 1,241 + 359 = 1,600.
Final Answer: The calculation 345 + 641 + 255 + 359 mentally performed step by step yields a total of 1,600.
Note: The specific laws, definitions, and axioms used in each step may vary. The general concept is to apply the basic addition operation repeatedly to calculate the final sum.
