Vocabulary and conceptual flashcards derived from the Year 7 Mathematics Level 2 Assessment Task, covering decimals, percentages, place value, and basic algebraic expressions.

Working line to find $23\%$ of $95$

$$\frac{23}{100} \times 95$$

Eighty-three and sixty-five hundredths

$$83.65$$

Multiplying a decimal by $100$

The decimal place moves two places to the right.

Ascending order

Arranging values from smallest to largest; for example, $0.05, 0.06, 0.5, 0.52, 0.6$.

Expression for '$x$ is doubled and then $3$ is added'

$$2x + 3$$

Place value of the digit $9$ in $27.491$

Hundredths

Numeral for 'fifteen and eight-tenths'

$$15.8$$

Numeral for 'six and nine-hundredths'

$$6.09$$

Rounding $1.8295$ to 1 decimal place

$$1.8$$

Rounding $1.8295$ to 2 decimal places

$$1.83$$

Rounding $1.8295$ to 3 decimal places

$$1.830$$

$0.09$ as a percentage

$$9\%$$

$152\%$ as a decimal

$$1.52$$

Division by $100$ (e.g., $23.47 \div 100$)

Moving the decimal point two places to the left, resulting in $0.2347$.

Coefficient

The number multiplied by a variable in an algebraic term; in $6x + 3y - 8z + 3$, the coefficient of $y$ is $3$ and the coefficient of $z$ is $-8$.

Constant term

A term in an algebraic expression that does not contain a variable; in $6x + 3y - 8z + 3$, it is $3$.

Terms in an expression

Individual components separated by plus or minus signs; the expression $6x + 3y - 8z + 3$ has 4 terms.

Like terms

Terms that contain the same variables; for example, $3cd$ and $18dc$ are like terms, but $14cd$ and $14ef$ are not.

Collecting like terms ($11m + 2n - m + n$)

Simplifying by combining terms with the same variable, resulting in $10m + 3n$.

Algebraic product of $4x$ and $6y$

$$24xy$$

Expression for '10 more than $4y$'

$$4y + 10$$

Expression for '8 less than $y$'

$$y - 8$$

Difference

The result of subtracting one number from another, such as the difference between $8.29$ and $5.7$ being $2.59$.

Quotient of $698.64 \div 1.23$ given $568 \times 123 = 69864$

$$568$$
