Answer 1

Given the expression 8___2___1___3___4 = 5

We are to substitute the signs into the blank spaces that will make the statement true

The correct substitute is as shown

$8\frac{.}{.}2\times1-3+4$

Solving using PEDMAS to confirm

P is parenthesis

E is exponent

D is division

M is multiplication

A is addition

S is subtraction

Solving based on the precedence;

= (8/2)*1-3+4

= (4*1)-3+4

= 4 - 3 + 4

= (4-3) + 4

= 1 + 4

= 5

Hence the order of operation is :, X, -, +
