Question

Evaluate 80 × a-2 for a = 4.

Answer 1

use correct parenthesis

Answer 2

i can only assume 80a - 2

Answer 3

80*(4-2)= 80*2 =160

Answer 4

if it is of form 80(a-2)

Answer 5

According to BODMAS rule we can solve this problem
first 80*a then from that sub -2
80*4=320
then 320-2=318

Answer 6

if 80*a-2= 80*4-2= 320-2 =318

Answer 7

\[80 \times a-2\]Where a = 4, so the equation turns to...\[80 \times 4-2\]Then, you go on and remember to use PEMDAS:\[80 \times 4-2\]\[320-2\]\[318\]And you're done. Simple as that. ;]
