Solve The Following Order Of Operations Questions 62322 Solve T

Identify the core assignment: solve a series of mathematical problems involving the order of operations and property identification, including simplifications and property names. Remove any repetitive, unclear, or incomplete questions. The main focus is on evaluating expressions using the correct order of operations, simplifying algebraic expressions, and naming algebraic properties.

Paper For Above instruction

The assignment requires solving several arithmetic expressions and algebraic problems involving the order of operations, simplification, and property recognition. This involves proceeding through calculations systematically according to PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right), simplifying algebraic expressions, and identifying the properties used in given algebraic examples.

First, for the arithmetic problems, each expression must be approached carefully, adhering to the correct order of operations. For example, in the expression -62+32, multiplication is performed first, followed by addition. Similarly, in -19+(-4)-9, multiplication takes precedence before addition; negative signs need careful handling. Attention is needed to handle negative numbers, division, and multiplication correctly, especially when signs are involved.

Second, the problems also include simplifying exponents, such as (3/2)3. This requires raising the fraction to the power of 3, which involves cubing both numerator and denominator (if necessary). Another is to recognize and name algebraic properties, such as the associative, distributive, or commutative properties, based on given expressions like 51=5, or 5(x+2)=5x+10, and 23=3*2.

For complex algebraic expressions and property identification, understanding fundamental properties like the distributive property, the associative property, and the commutative property is crucial. Properly naming these properties with their formal definitions demonstrates a clear understanding of algebraic principles.

Full solution to the above problems

1) -6*2+32

Using PEMDAS, perform multiplication first: -6*2 = -12. Then addition: -12+32 = 20.

2) -19 + (-4)*-9

Multiply first: -4 * -9 = 36 (product of two negatives is positive). Then add: -19 + 36 = 17.

3) -6 - 7*8

Multiply first: 7*8=56. Then subtract: -6 - 56 = -62.

4) 300/-15 + 36

Division first: 300 / -15 = -20. Add 36: -20 + 36 = 16.

5) 85/-17 + (-15)

Division first: 85 / -17 = -5. Then sum: -5 + (-15) = -20.

6) -2 - 34 / -2

Division first: 34 / -2 = -17. Now, -2 - (-17) = -2 + 17 = 15.

7) 150 / (incomplete, assuming missing expression, skip or assume 150 / 1 = 150)

An incomplete expression is provided, so cannot solve. Moving to next.

8) -14 + (-3)*4

Multiply: (-3) * 4 = -12. Then add: -14 + (-12) = -26.

9) -25 * (-)

Incomplete expression; cannot solve.

10) -18 + (-3) - 2 * 4 - 3 / -3

Following order: multiplication and division first.

-2 * 4 = -8

3 / -3 = -1

Now compute step-by-step: -18 + (-3) = -21

-21 - 8 = -29

-29 - 1 = -30

11) Simplify (3/2)3

Cube numerator and denominator: (33) / (23) = 27/8.

12) Simplify (-)

Incomplete expression; cannot be solved.

13) Name the Property 5 * 1 = 5

This demonstrates the Multiplicative Identity Property, which states that any number multiplied by 1 remains unchanged.

14) Name the Property 5(x+2) = 5x + 10

This illustrates the Distributive Property, which distributes multiplication over addition.

15) Name the Property 2 3 = 3 2

This demonstrates the Commutative Property of Multiplication, which states that the order of factors doesn't affect the product.

Conclusion

This exercise highlights the importance of understanding the order of operations in mathematical expressions and the properties of algebra that underpin various simplifications. Correctly applying PEMDAS ensures accurate computation, while recognizing properties like distributive, associative, and commutative properties deepens algebraic comprehension. Mastery of these fundamental concepts is essential for solving complex mathematical problems efficiently and reliably.
