Which of these is equal to 50 + 21?<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Correct Answer:<\/strong><\/p>\n\n\n\n

The correct answer to 50 + 21<\/strong> is 71<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

To solve 50 + 21<\/strong>, we are performing a basic arithmetic operation called addition<\/strong>. Addition is one of the four fundamental operations in mathematics, along with subtraction, multiplication, and division. It involves combining two numbers, known as addends<\/strong>, to get a sum<\/strong>.<\/p>\n\n\n\n

In this case:<\/p>\n\n\n\n

    \n
  • The first addend is 50<\/strong>.<\/li>\n\n\n\n
  • The second addend is 21<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    We can calculate this directly:<\/p>\n\n\n\n

      \n
    • Start with 50<\/strong>.<\/li>\n\n\n\n
    • Add 21<\/strong> more to it.<\/li>\n<\/ul>\n\n\n\n

      Let\u2019s break down the second number, 21<\/strong>, into two parts to make the addition easier:<\/p>\n\n\n\n

        \n
      • 21 = 20 + 1<\/li>\n<\/ul>\n\n\n\n

        Now, add them step by step:<\/p>\n\n\n\n

          \n
        1. 50 + 20 = 70<\/li>\n\n\n\n
        2. 70 + 1 = 71<\/strong><\/li>\n<\/ol>\n\n\n\n

          So, 50 + 21 = 71<\/strong>.<\/p>\n\n\n\n

          \n\n\n\n

          Why This Works:<\/h3>\n\n\n\n

          We are using place value<\/strong>\u2014the concept that numbers are made up of digits that each represent a different power of 10 depending on their position.<\/p>\n\n\n\n

            \n
          • 50 has a 5 in the tens place, meaning 5 \u00d7 10 = 50<\/li>\n\n\n\n
          • 21 has a 2 in the tens place (2 \u00d7 10 = 20) and 1 in the ones place (1 \u00d7 1 = 1)<\/li>\n<\/ul>\n\n\n\n

            When we add tens to tens (50 + 20), we get 70. Adding the remaining 1 gives us the final sum of 71.<\/p>\n\n\n\n

            \n\n\n\n

            Real-Life Relevance:<\/h3>\n\n\n\n

            Knowing how to add numbers like 50 and 21 is crucial in everyday life. Whether you\u2019re adding up money, measuring distances, calculating time, or combining quantities, addition helps you keep accurate totals. For example, if you buy an item that costs $50 and another for $21, you’ll pay $71 in total.<\/p>\n\n\n\n

            Thus, mastering this basic arithmetic skill is essential not only in math but in practical daily situations.<\/p>\n\n\n\n

            \u2705 Final Answer: 71<\/strong><\/p>\n\n\n\n
