Q & A
What are the two common terms for the symbol used for addition in English?
-The two common terms for the addition symbol are 'plus' and 'add'.
How is the subtraction symbol represented when reading an equation in English?
-The subtraction symbol is represented as 'minus' or 'take away' when reading an equation in English.
What do you call the symbol 'x' in English when reading mathematical expressions?
-The symbol 'x' is referred to as 'times' or simply 'x' when reading mathematical expressions in English.
How is the division symbol '/' pronounced in English?
-The division symbol '/' is pronounced as 'over' or 'slash' in English.
How do you read a fraction like 'x squared over Y to the power of four'?
-You would read 'x squared over Y to the power of four' as 'x squared divided by Y to the fourth power' or 'x squared over Y to the power of four'.
What are the different terms used for brackets in English according to the script?
-In English, 'brackets' can be referred to as 'parentheses', with 'Americans' more likely to use 'parentheses' and 'Australians' using 'brackets'.
How do you read an equation with a power such as 'x to the power of n'?
-An equation with a power such as 'x to the power of n' is read as 'x to the power of n', regardless of the specific number replacing 'n'.
Can you provide an example of how to read an equation with a power and division?
-An example of reading such an equation would be 'X plus 7 over Y to the power of 2', pronounced as 'X plus 7 divided by Y squared'.
How do you read an equation with brackets in English?
-In English, you would say 'open bracket' before the expression inside the brackets and 'closed bracket' after it, like 'open bracket XYZ close bracket' or 'the expression inside, all in brackets'.
What is the process for solving an equation like '11 plus x over X cubed'?
-To solve the equation '11 plus x over X cubed', you would first subtract 11 from both sides, then expand the right side by multiplying the 2 through the expression inside the brackets, and finally solve for 'x' by multiplying and dividing appropriately.
Why is it important to specify 'open bracket' and 'closed bracket' when reading equations with parentheses?
-Specifying 'open bracket' and 'closed bracket' helps to clarify where the parentheses start and stop, making the equation easier to understand and follow.
How can you enhance clarity when reading equations with parentheses?
-Enhancing clarity when reading equations with parentheses involves explicitly stating 'open bracket' and 'closed bracket' or 'open parentheses' and 'closed parentheses' to clearly indicate the boundaries of the expression within the parentheses.
Outlines
π Understanding Mathematical Symbols and Reading Equations in English
This paragraph serves as an instructional guide on how to read equations in English, focusing on interpreting mathematical symbols and expressions. It begins with the basic arithmetic operations, explaining that '+' is read as 'plus' or 'add', and '-' as 'minus' or 'take away'. The multiplication symbol 'x' or a dot and the division symbols '/' or 'over' are also covered. The explanation extends to powers, where the term 'squared' is used for exponents of two, 'cubed' for three, and 'to the power of n' for any other exponent. The instructor gives examples of reading fractions and powers, such as 'x squared over y to the power of four'. Attention is then shifted to parentheses (or brackets), noting the differences in terminology between American (parentheses) and Australian (brackets) English. The usage of 'open' and 'closed' brackets is demonstrated, along with how to read expressions inside them, such as 'XYZ all in parenthesis'. The paragraph ends with an example problem to practice reading equations aloud.
π’ Advanced Examples and Solving Equations Using English Terms
The second paragraph dives deeper into reading and solving mathematical expressions in English. It starts with simpler examples, like '2 to the power of y times x', and moves to more complex ones incorporating multiple rules, such as '11 plus x over x cubed plus 2x times (5 minus x)'. The narrator emphasizes clarity in verbalizing equations, preferring to specify 'open' and 'close' brackets to avoid ambiguity. The lesson progresses to applying these skills in solving an equation. It illustrates the steps involved in solving, such as subtracting 11 from both sides, expanding expressions, and isolating the variable x. The process demonstrates how mathematical operations are verbalized in English, like 'multiply both sides by -1' or 'divide both sides by 2'. The paragraph concludes with the narrator expressing hope that the lesson will be helpful and inviting viewers to revisit the video for reinforcement.
