    -The result of a division equation is called a 'quotient'.

  • How are brackets used in equations and how are they read?

    -Brackets are used in equations to indicate that the numbers inside them should be considered as a group and performed first. They are read as 'in brackets'. For example, in the equation '1 + (2 x 3) = 9', it is read as 'one plus two in brackets times three equals nine'.

  • What are the different symbols that can be used instead of an equals sign in equations?

    -Instead of an equals sign, you can use 'not equal to', 'greater than', 'smaller than', 'greater than or equal to', 'smaller than or equal to', and 'approximately equal to' symbols in equations.

  • How is a fraction read in English?

    -A fraction is read by saying the numerator as a cardinal number and the denominator as an ordinal number. If the numerator is greater than 1, 's' is added to the ordinal number. For example, the fraction '1/5' is read as 'one-fifth'.

  • What is the correct way to read a decimal number?

    -A decimal number is read by saying the number before the decimal point, followed by the word 'tenths' for the first digit after the decimal point, and then each subsequent digit. For example, '0.7' is read as 'zero point seven', and '0.727' is read as 'seven tenths, two hundred twenty-sevenths'.

  • How is a square root sign represented and read?

    -A square root sign is represented by the radical sign. It is read as 'the square root of' followed by the number under the sign. For example, '√4' is read as 'the square root of four'.

  • What is an exponent and how is it read in an equation?

    -An exponent is a small value that indicates how many times the base number should be multiplied by itself. It is read by saying the base number followed by 'squared' for an exponent of 2, 'cubed' for an exponent of 3, or 'to the power of' for any other exponent value. For example, '4^3' is read as 'four cubed'.
