Answer 1

Ответ:

Пошаговое объяснение:

1)=-56+6*(-54)+(-44)+283=-56-324-44+283=-141

2)=-28-(-19)*(-6)+91=-28-144+91=-81

3)=70-345+145=-130

4)584:(-2)-225:(-15)-78=-274+15-78=-337

Answer 2

Let's solve each expression step by step:

1. -56 + 6 * (-73 + 19) + 176 / (-4) + 283

Step 1: Simplify the innermost parentheses: -73 + 19 = -54 Step 2: Evaluate the multiplication: 6 * (-54) = -324 Step 3: Evaluate the division: 176 / (-4) = -44 Step 4: Add the numbers: -56 + (-324) + (-44) + 283 = 187

So, the result is 187.

2. 196 / (-7) - (283 - 302) * (-6) + 91

Step 1: Evaluate the division: 196 / (-7) = -28 Step 2: Simplify the innermost parentheses: 283 - 302 = -19 Step 3: Evaluate the multiplication: -19 * (-6) = 114 Step 4: Add the numbers: -28 + 114 + 91 = 177

So, the result is 177.

3. -280 / (-4) + 69 * (-5) - 725 / (-25)

Step 1: Evaluate the division: -280 / (-4) = 70 Step 2: Evaluate the multiplication: 69 * (-5) = -345 Step 3: Evaluate the division: -725 / (-25) = 29 Step 4: Add the numbers: 70 + (-345) + 29 = -246

So, the result is -246.

4. (-283 + 997) / (-2) - 225 / (-15) - 78

Step 1: Evaluate the addition inside the parentheses: -283 + 997 = 714 Step 2: Evaluate the division: 714 / (-2) = -357 Step 3: Evaluate the division: 225 / (-15) = -15 Step 4: Subtract the numbers: -357 - (-15) - 78 = -264

So, the result is -264.
