Solution 4

a) 137 and – 354

= 137 + (-354)

= -217

b) – 52 and 52

= -52 + 52

= 0

c) – 312, 39 and 192

= -312 + 39 + 192

= -81

d) – 50, – 200 and 300

= -50 + (-200) + (300)

= 50

Answer 2

Answer:

$52+(-7)+(-91)+(-12)=-58$.

Step-by-step explanation:

Given sum is $52+(-7)+(-91)+(-12)$.

While solving arithmetic operations, we use the BODMAS rule,

B - Brackets

O - Orders

D - Division

M - Multiplication

A - Addition

S - Subtraction

We apply the BODMAS rule and find the sum,

First in the order let us solve the brackets,

We know the product of a negative and a positive symbol is always negative,

$52-7-91-12$

Now it is a straight forward subtraction,

$=45-91-12$

$=-46-12$

$=-58$

The sum is $-58$.
