Step 1: Identify the numbers to be added. We have the number 2 and the number 6. Step 2: Understand the operation. The plus sign (+) means we combine the two numbers together. Step 3: Combine the numbers. Start with 2 and count forward 6 more: 2 → 3 (1 more), 4 (2 more), 5 (3 more), 6 (4 more), 7 (5 more), 8 (6 more). Step 4: State the result. After adding 6 to 2, we reach 8. Step 5: Final answer. 2 + 6 = 8
We are adding two numbers: 15 and 4. Step 1: Write the problem clearly. 15 + 4 Step 2: Start with the larger number, which is 15. We will add 4 to it. Step 3: Break the addition into counting up. From 15, count up 4 more: 15 → 16 (1 more), 16 → 17 (2 more), 17 → 18 (3 more), 18 → 19 (4 more). Step 4: After counting up 4 from 15, we reach 19. Step 5: Check the result: 15 + 4 = 19. Final Answer: 19
Step 1: Identify the numbers to be added. We have the first number: 2, and the second number: 4. Step 2: Understand the operation. The plus sign (+) means we combine the two numbers to find the total. Step 3: Start counting from the first number. Begin at 2, then count up 4 more: 2 → 3 (first count), 3 → 4 (second count), 4 → 5 (third count), 5 → 6 (fourth count). Step 4: State the result. After counting up 4 from 2, we reach 6. Step 5: Final answer. Therefore, 2 + 4 = 6.
We are told there is a rectangle with 4 rows of circles, and each row has 3 circles. Step 1: Understand the arrangement. - There are 4 rows. - Each row contains 3 circles. Step 2: Determine the total number of circles. To find the total, we multiply the number of rows by the number of circles in each row: Total circles = number of rows × circles per row Total circles = 4 × 3 Step 3: Perform the multiplication. 4 × 3 = 12 Step 4: State the final answer. There are 12 circles in total.
We are adding two numbers: 3 and 11. Step 1: Write the numbers in a vertical alignment mentally to see the addition clearly. 3 + 11 Step 2: Start by adding the digits in the ones column (rightmost column). The number 3 has 3 ones. The number 11 has 1 one. 3 ones + 1 one = 4 ones. Write down 4 in the ones place of the answer. Step 3: Now move to the tens column. The number 3 has 0 tens. The number 11 has 1 ten. 0 tens + 1 ten = 1 ten. Write down 1 in the tens place of the answer. Step 4: Combine the tens digit and ones digit: 1 ten and 4 ones makes 14. Therefore, 3 + 11 = 14.
We are adding the numbers 3 and 4. Step 1: Start with the first number: 3. Step 2: Add the second number, which is 4, to the first number. Step 3: To do this, you can count up from 3: 3 → 4 (1 more), 5 (2 more), 6 (3 more), 7 (4 more). Step 4: After adding 4 to 3, the total is 7. Therefore, 3 + 4 = 7.
Step-by-step solution: Step 1: Identify the numbers in the problem We have two numbers: 0 and 1 Step 2: Understand the operation The plus sign (+) tells us we need to perform addition Step 3: Recall the addition property of zero Adding zero to any number does not change that number's value. This is called the additive identity property. Step 4: Apply this property When we add 0 to 1, the result is simply 1 Step 5: Write the calculation 0 + 1 = 1 Step 6: Verify the answer We can think of this as starting at 1 and adding nothing (0), so we remain at 1. Therefore, the correct answer is 1.
Step 1: Identify the numbers to be added. We have the first number: 0. We have the second number: 0. Step 2: Understand the meaning of adding zero. Adding zero to any number does not change its value. For example, 5 + 0 = 5, 2 + 0 = 2, etc. Step 3: Apply this rule to our problem. Here, the first number is 0, and we are adding 0 to it. So, 0 + 0 means we start at 0 and add nothing. Step 4: Perform the addition. 0 + 0 = 0. Step 5: Conclusion. The sum of zero and zero is zero. Final Answer: 0
