Solving a Mathematical Expression Following Order of Operations
当然，解决这个数学问题，我们需要遵循运算法则顺序，即乘法和除法优先于加法和减法。 1. 6 - (1×0) + (2÷2) 2. 6 - 0 + 1 3. 6 + 1 4. 7 答案是7。
Solving an Equation Using PEMDAS Order of Operations
To solve the equation in the image, follow the order of operations, commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Division and multiplication are done from left to right, as are addition and subtraction. The equation is: 9 - 3 ÷ (1/3) + 1. Now, let's solve it step by step: 1. First, perform the division: 3 ÷ (1/3). Since dividing by a fraction is the same as multiplying by its reciprocal, this becomes 3 * (3/1), which equals 9. 2. Now, replace the division part with the result, 9: 9 - 9 + 1. 3. Then, perform the subtraction: 9 - 9 equals 0. 4. Finally, perform the addition: 0 + 1 equals 1. So, the answer to the equation is 1.
Order of Operations Example
To solve the expression in the image, you should follow the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). The expression is: 90 ÷ 2 + 4 According to the order of operations, division comes before addition, so you first need to divide 90 by 2: 90 ÷ 2 = 45 Next, you add 4 to the result: 45 + 4 = 49 So, the solution to the expression is 49.
Solving Equations using PEMDAS
To solve the equation, follow the order of operations, often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Here's how you solve the provided equation following PEMDAS: 1. Parentheses first: calculate the expression inside the parentheses. \( 5 + 2 = 7 \) 2. Then multiplication: \( 4 \times 7 = 28 \) 3. Lastly, addition: \( 28 + 8 = 36 \) Therefore, the solution to the equation is 36.
Order of Operations Example
According to the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), you should perform multiplication before addition. So, for the expression \(3 + 4 \times 8\), you would first multiply 4 by 8. \(4 \times 8 = 32\) After that, you add 3 to the result. \(3 + 32 = 35\) Therefore, \(3 + 4 \times 8 = 35\).
Solving a Mathematical Expression Using PEMDAS Order of Operations
To solve this mathematical expression, follow the order of operations, which can be remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Let's solve it step-by-step: 1. Start with the parentheses: \( (2 + 2) = 4 \) 2. Then, according to PEMDAS, we need to do the division next since it comes before multiplication in the order of operations: \( 8 ÷ 2 = 4 \) 3. Now, multiply the result of the division by the result from the parentheses: \( 4 × 4 = 16 \) Therefore, the answer to the expression is 16.
