What is the value of (3 + 5) × 2? — 16.First evaluate the parentheses: 3 + 5 = 8. Then multiply: 8 × 2 = 16.
Which symbol represents the innermost grouping in a nested expression? — Parentheses ( ).Parentheses ( ) are the innermost grouping symbols and are evaluated first.
What word problem phrase matches the expression (8 − 3) × 4? — Multiply the difference of 8 and 3 by 4."Difference of 8 and 3" = (8 − 3). "Multiply by 4" gives (8 − 3) × 4.
What does the word "product" indicate in a word problem? — Multiplication."Product" is the result of multiplication, so it signals a × operation.
Which expression equals "the sum of 9 and 3"? — 9 + 3."Sum" means addition, so the sum of 9 and 3 is 9 + 3.
What is the value of 3 + 5 × 2 (no parentheses)? — 13.Without parentheses, multiply first: 5 × 2 = 10. Then add: 3 + 10 = 13.
Which word means subtraction in a math expression? — Difference."Difference" is the result of subtraction, so it signals a − operation.
How many grouping levels are in { [ (5 + 3) × 2 ] − 4 }? — 3.Three levels: ( ) innermost, [ ] middle, { } outermost.
Evaluate: { [ (2 + 3) × 4 ] − 6 } — 14.(2+3)=5. [5×4]=20. {20−6}=14. This is the nested example from the lesson.
What does the order of grouping symbols tell you? — Which operations to perform first.Grouping symbols like ( ), [ ], and { } tell you which operations must be evaluated first.
What does PEMDAS stand for? — Parentheses, Exponents, Multiply/Divide, Add/Subtract.PEMDAS: Parentheses, Exponents, Multiplication & Division (left to right), Addition & Subtraction (left to right).
Which operation is performed first in: 5 + 4² − 3? — Exponent (4²).PEMDAS: Exponents come before addition and subtraction.
In PEMDAS, when you reach multiplication and division, you: — Work left to right.Multiplication and division have equal priority — work left to right.
Which mnemonic helps remember PEMDAS? — Please Excuse My Dear Aunt Sally.The classic mnemonic is "Please Excuse My Dear Aunt Sally" for P-E-M-D-A-S.
What is an ordered pair? — Two numbers (x, y) that give a location on a grid.An ordered pair (x, y) gives the exact location of a point on a coordinate grid.
In the ordered pair (5, 3), which value is plotted along the x-axis? — 5.The first number in an ordered pair is the x-value, plotted along the horizontal x-axis.
Pattern A: 0, 1, 2, 3. Pattern B: 0, 2, 4, 6. What is the rule for Pattern B? — Add 2 each time.0+2=2, 2+2=4, 4+2=6. The rule is "add 2."
Using Pattern A (add 1) and Pattern B (add 2) from above, what is the 5th ordered pair? — (4, 8).The 5th term of A (starting at 0) is 4. The 5th term of B is 8. Ordered pair: (4, 8).
When plotting (x, y), you move _____ along the x-axis and then _____ along the y-axis. — right, up."Run before you jump" — move right along x first, then up along y.
The origin of a coordinate grid is at: — (0, 0).The origin is the point where both axes cross, at coordinates (0, 0).
Pattern A: 1, 2, 3, 4. Pattern B: 5, 10, 15, 20. What is the relationship? — B is always 5 times A.5/1=5, 10/2=5, 15/3=5, 20/4=5. B is always 5 times A.
What does "consecutive terms" mean? — Terms that come one after another in a sequence.Consecutive terms are terms that appear one immediately after another in a sequence, like the 3rd and 4th terms.
If y is always 4 more than x, and x = 7, what is y? — 11.y = x + 4 = 7 + 4 = 11.
