It means you have to solve the problem in parentheses first.
ex: 2X4+5= 13; 2X (4+5) = 18. The answer is different because
you have to solve the problem in the Order of Operations.
1) Parentheses
2) Exponents like 22
3) Multiplication
4) Division
5) Addition
6) Subtraction
PEMDAS or Please Excuse My Dear Aunt Sally.
Parentheses are brackets which are rounded kind. Like the one below: ( ..... )
No. Parentheses have no direct effect on the sign of a number.
the number with the variable. For example, in 6x, the coefficient is 6.
maybe it is question 1 and question 2
(43 - 19) + (16 - 14)(4)= 24 + (2)(4)= 24 + 8= 32
Parentheses are brackets which are rounded kind. Like the one below: ( ..... )
Parentheses are used in math number models to indicate the order in which mathematical operations should be performed. They help clarify the intended meaning of the equation and ensure that calculations are done correctly according to the rules of arithmetic.
removing the parentheses in a math problem
Parentheses are used to mean whispered, or an afterthought. Or in Math, to be figured separately from the first part of the equation.
understand, plan, solve,& check
p stands for parentheses and e stands for exponents
When the terms in a polynomial are commutative, they can be grouped with parentheses in any way.
Parentheses and brackets work the same in math as they do in writing -- use them to group ideas.
the number is negative.
Brackets or parentheses.
use parentheses when u do a opperation. Parentheses have to do 1st no matter what
Too many variables to really answer. The context of the number is critical. Is it an Area Code? Is it a negative number on a bank statement? Is it referencing a footnote in a book? Is it following a number such as one (1)? The meaning is entirely dependant on the context. ______________________________________________________________________ Another answer would be that if a number in parentheses is right next to another number, then you are to multiply both numbers if it's a math problem. In some graph tables, f(x) replaces y. Variables, letters that replace numbers, can also be in parentheses.
