How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What is the value of $-6 \times 7$?

Answer: $-42$. Multiplying a negative by a positive yields a negative product.

Flashcard 2: What is the value of $\left(-3\right)^2 - 4 \times 2$?

Answer: $1$. Order of operations: exponent first to get 9, then multiply, then subtract.

Flashcard 3: What is the value of $\frac{7}{9}$ of $63$?

Answer: $49$. Multiply the fraction by the number, simplifying by dividing 63 by 9 first.

Flashcard 4: What is the value of $\frac{3}{4} + \frac{1}{8}$?

Answer: $\frac{7}{8}$. To add fractions, convert to a common denominator of 8 and sum the numerators.

Flashcard 5: What is the value of $\frac{3}{2} \div \frac{9}{4}$?

Answer: $\frac{2}{3}$. Dividing fractions means multiplying by the reciprocal, then simplifying by dividing by 3.

Flashcard 6: What is the value of $\frac{11}{12} - \frac{5}{8}$?

Answer: $\frac{7}{24}$. Subtract fractions using a common denominator of 24 and subtracting numerators.

Flashcard 7: What is the value of $-56 \div 8$?

Answer: $-7$. Dividing a negative by a positive yields a negative quotient.

Flashcard 8: What is the value of $-7 + 12$?

Answer: $5$. Adding a positive number to a negative number results in subtracting the absolute value of the negative from the positive.

Flashcard 9: What is the value of $-18 - (-5)$?

Answer: $-13$. Subtracting a negative is equivalent to adding its positive counterpart, so $-18 + 5 = -13$.

Flashcard 10: What is the value of $( -4 + 9 ) \times 2$?

Answer: $10$. Parentheses are evaluated first, then multiplication.

Flashcard 11: What is the value of $5.2 - 7.85$?

Answer: $-2.65$. Subtracting a larger decimal from a smaller one results in a negative value.

Flashcard 12: What is the value of $\frac{5}{6} - \frac{1}{3}$?

Answer: $\frac{1}{2}$. Subtract fractions by converting to a common denominator of 6 and subtracting numerators, then simplify.

Flashcard 13: What is the value of $0.7 \times 0.08$?

Answer: $0.056$. Multiply decimals by ignoring decimals initially, then placing the point based on total decimal places.

Flashcard 14: What is the value of $\frac{2}{5} + \frac{3}{10}$?

Answer: $\frac{7}{10}$. Add fractions with a common denominator of 10 by summing numerators.

Flashcard 15: What is the value of $\frac{3}{5}$ of $40$?

Answer: $24$. 'Of' indicates multiplication of the fraction by the whole number.

Flashcard 16: What is the value of $4.2 \div 0.7$?

Answer: $6$. Dividing decimals is equivalent to $42 \div 7 = 6$ after adjusting for the decimal.

Flashcard 17: What is the value of $120\%$ of $50$?

Answer: $60$. Percent greater than 100 means multiplying by a decimal larger than 1.

Flashcard 18: What is the value of $18 - 6 \div 3$?

Answer: $16$. Order of operations requires division before subtraction.

Flashcard 19: What is the value of $48 \div 6 \times 3$?

Answer: $24$. Follow order of operations: divide first, then multiply left to right.

Flashcard 20: What is the value of $\frac{7}{8} \div \frac{14}{3}$?

Answer: $\frac{3}{16}$. Dividing fractions involves multiplying by the reciprocal, then simplifying by dividing by 7.

Flashcard 21: What is the value of $\left(\frac{3}{4} - \frac{1}{2}\right) \div \frac{1}{8}$?

Answer: $2$. Evaluate parentheses first to get $\frac{1}{4}$, then divide by multiplying by the reciprocal.

Flashcard 22: What is the value of $3.6 + 0.45$?

Answer: $4.05$. Add decimals by aligning the decimal points and summing the digits.

Flashcard 23: What is the value of $25\%$ of $80$?

Answer: $20$. Percent of a number is found by converting percent to decimal and multiplying.

Flashcard 24: What is the value of $15 - 23$?

Answer: $-8$. Subtracting a larger positive number from a smaller one yields a negative result.

Flashcard 25: What is the value of $\frac{2}{3} \times \frac{9}{10}$?

Answer: $\frac{3}{5}$. Multiply fractions by multiplying numerators and denominators, then simplify by dividing by 6.
