1+1=2
Correct Answer
A. True
Explanation
The equation "1+1=2" is a basic example of addition in mathematics. In simple terms, when we add 1 and 1 together, the result is always 2. This is one of the most fundamental facts in arithmetic, and it is universally accepted in all basic math systems. Addition is a simple process where two numbers are combined to form a total, and in this case, the total is 2. This rule holds true in everyday life as well as in more advanced mathematical operations. Therefore, the answer to this equation is True.

5+5=10
Correct Answer
A. True
Explanation
The equation "5+5=10" represents a simple addition problem. When we add 5 and 5 together, we get 10. This is an elementary mathematical sum that is part of the foundation of arithmetic. Addition involves combining two numbers to get a larger number, and in this case, the sum of 5 and 5 equals 10. This fact is true and is an example of the basic addition rule that we use every day. It is an accurate statement, and the correct answer is True.
3.
8+8=16
Correct Answer
A. True
Explanation
In the equation "8+8=16," we are adding 8 to 8. The sum of 8 and 8 is indeed 16, which is mathematically accurate. Addition is a simple operation where we combine two numbers to find the total. Here, when you add two 8's together, you get 16. This is a basic example of doubling, where we are adding the same number twice. The concept of doubling is used in many areas of math and real-life situations. This addition is correct, so the answer is True.
4.
10+10+10=30
Correct Answer
A. True
Explanation
The equation "10+10+10=30" shows the addition of three tens. When you add 10, 10, and 10 together, the total is 30. This is a straightforward example of adding the same number multiple times. Addition is a process where we calculate the total by combining several numbers, and here, when you add 10 three times, you get 30. This is a basic math principle and follows the rules of arithmetic. Since the sum is correct, the statement is True.
5.
7+7=14
Correct Answer
A. True
Explanation
The equation "7+7=14" is correct. When we add 7 and 7, the sum is indeed 14. This is a basic addition problem, and it’s important to remember that when you add two identical numbers together, the result is always double that number. In this case, doubling 7 gives you 14. Addition like this is an important part of arithmetic, and learning to add numbers efficiently is one of the first steps in mastering math. Therefore, the answer to this equation is True.
6.
4+3=8
Correct Answer
B. False
Explanation
The equation "4+3=8" is incorrect. When you add 4 and 3 together, the correct sum is 7, not 8. This is an example of a simple addition mistake. When adding two numbers, it’s important to carefully calculate the result. In this case, 4 plus 3 equals 7. This is a basic arithmetic error that we often make when we are not paying attention to the numbers. Since the sum does not equal 8, the correct answer is False.
7.
1+8=9
Correct Answer
A. True
Explanation
The equation "1+8=9" is true. When you add 1 and 8 together, the result is 9. This is a basic addition problem where two numbers are combined to get a sum. Addition is one of the most fundamental operations in math, and this equation shows how easy it is to add smaller numbers. The process of adding 1 to 8 is straightforward, and the correct sum is indeed 9. Therefore, the correct answer is True.
8.
12÷3=4
Correct Answer
A. True
Explanation
The equation "12÷3=4" is correct. When you divide 12 by 3, the result is 4. Division is the process of splitting a number into equal parts, and here we are dividing 12 into 3 equal parts. Each part equals 4, so the statement is true. Division is the opposite of multiplication, and it is an essential operation in math. In this case, dividing 12 by 3 gives a result of 4, and the equation is therefore True.
9.
1×4=5
Correct Answer
B. False
Explanation
The equation "1×4=5" is incorrect. When you multiply 1 by 4, the correct product is 4, not 5. This is a simple multiplication error. Multiplication is a math operation where you add a number to itself a certain number of times, depending on the multiplier. In this case, multiplying 1 by 4 means adding 1 four times, which equals 4. Since 1×4 does not equal 5, the statement is False.
10.
1+9=10
Correct Answer
A. True
Explanation
The equation "1+9=10" is correct. When you add 1 and 9 together, the sum is 10. This is a basic addition fact, and it’s one of the simplest operations in math. Addition involves combining two numbers to get a total, and in this case, the total is 10. This fact is foundational in arithmetic and is widely used in many areas of math. Since the sum is accurate, the correct answer is True.
