Using each of the digits 1, 2, 3, and 4 once and only once, with the basic rules of arithmetic (+, -, ÷, x, and parentheses). i already have 3+2-1=4 and 4÷2+1=3. i need one more! !

3 +(2 -1) =4

Step-by-step explanation:

Another method is

(2-1) + 3 = 4

1 + (4 ÷ 2) = 3

(3 +2) -1 =4

3 +(2-1) =4

( 3 + 2) - 4 = 1

3 + (2 -4) = 1

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
