Question

2. Simplify the following mathematical
expressions.
a) 42 – [20 – {19 – (14 – 8 – 4)}]​

Answer 1

Answer:

▪︎Given -:

Simplify the following mathematical expression.

a) 42-[20-{19-(14-8-4)}]

▪︎Concept -:

See , use the formula of BODMAS .

B = Brackets

O = Of

D = Division

M = Multiplication

A = Addition

S = Subtraction

And in this equation first do sum of - integer . And then subtract the - integer with the + integer .

▪︎Solution -:

>> 42-[20-{19-(14-8-4)}]

(Do , sum of 8 and 4 then subtract with 14)

>> 42-[20-{19-(14-8+4)}]

>> 42-[20-{19-(14-12)}]

>> 42-[20-{19-2}]

>> 42-[20-17]

>> 42-3

>> 39

▪︎Answer -:

So , the answer of the following equation given is 39 .

Answer 2

Answer:

39

Step-by-step explanation:

GIVEN EXPRESSION:

42-[20-{19-(14-8-4)}]

WHAT TO DO:

SIMPLIFY IT.

CONCEPT :

BODMAS,

B=BRACKETS ( SQUARE,CURLY OR NORMAL BRACKETS)

O=OF

D=DIVISION

M=MULTIPLICATION.

A=ADDITION

S=SUBTRCTION.

LET'S SIMPLIFY IT:

42-[20-{19-(14-8-4)}]

=42-[20-{19-2}]

=42-[20-17]

=42-3=39 (ANSWER)
