What math sign is used before a negative number?
A minus sign '-'. Some authors distinguish the "take away" operation sign from the neg. number sign by making the latter shorter and higher. In accountancy neg. numbers can be written in brackets or colored red
When you subtract a negative from a negative does it make it positive?
There's no general rule. The result could be positive and it could also be negative. It depends on how big both numbers are. (neg 5) minus (neg 7) = pos 2 (neg 5) minus (neg 3) = neg 2
How do you find the quotient of two numbers when one is positive and the other is negative?
The answer is the normal quotient except negative. Pos X neg = neg
How do you answer order of operations with brackets?
You ALWAYS do whats in the brackets first! If there are parentheses in the bracket, you do the parentheses in the brackets first GLAD I COULD HELP :)
What do you use when writing the domain of real numbers brackets or squares?
When writing a range of numbers, square brackets are used to indicate the end number is included and round brackets are used to indicate the end number is excluded.examples:[1, 4] = all numbers ≥ 1 and ≤ 4(1, 4] = all numbers > 1 and ≤ 4[1, 4) = all numbers ≥ 1 and < 4(1, 4) = all numbers > 1 and < 4
