Four Operations Fluency - ISEE Middle Level: Mathematics Achievement

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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