Answer:
a. 2
b. 12
c. 36
d. 19
Step-by-step explanation:
a. 14 – 7 – 5 = 14 - 12 = 2
b. (35 – 20) – 3 = (15) -3 = 15 - 3 = 12
c. 45 – (23 – 14) = 45 - (9) = 45 - 9 = 36
d. 56 – 32 – 5 = 56 - 37 = 19
Hope it helps.
Thank you..!!
We are asked to simplify the expression that is given each of the four options.
a)
[tex]14-7-5[/tex]
We know that we need to first sum of 7 and 5 since they are the terms with the same sign i.e. negative sign.
Hence, on adding we get [tex]7+5=12[/tex]
Now we subtract this quantity by 14 to get:
[tex]14-12=2[/tex]
Hence, the answer is : 2
b)
[tex](35-20)-3[/tex]
Now we first solve the parentheses term.
i.e.
[tex]35-20=15[/tex]
and
[tex]15-3=12[/tex]
Hence, the answer is: 12
c)
[tex]45-(23-14)[/tex]
Now again using the rule of PEMDAS we first solve the parentheses term.
i.e.
[tex]23-14=9[/tex]
and on subtracting this quantity by 45 we get:
[tex]45-9=36[/tex]
Hence, the answer is: 36
d)
[tex]56-32-5[/tex]
We first add 32 and 5 since they are the terms with the same sign.
Hence, we get:
[tex]32+5=37[/tex]
and now on subtracting this term by 56 we get:
[tex]56-37=19[/tex]
Hence, the answer is: 19
