Answer 2

Ответ:

1)1500 :(500-200*2)=1500:(500-400)=1500:100=15

2)1500*(500-200):2=1500*300:2=1500*150=10

3)3546-283*4+819=3546-1132+819=2414+819=3233

4)1254+645:5-967=1254+129-967=1382-967=415

Answer 3

Let's solve each expression step by step:

1. 1500:(500-200*2)

First, perform the operation inside the parentheses: 500 - 200 * 2 = 500 - 400 = 100

Next, perform the division: 1500 : 100 = 15

So, the result of the expression is 15.

2. 1500*(500-200)

Again, perform the operation inside the parentheses: 500 - 200 = 300

Next, perform the multiplication: 1500 * 300 = 450000

So, the result of the expression is 450000.

3. 3546-283*4+819

Perform the multiplication first: 283 * 4 = 1132

Now, perform the addition and subtraction: 3546 - 1132 + 819 = 3413

So, the result of the expression is 3413.

4. 1254+645:5-967

Perform the division first: 645 : 5 = 129

Now, perform the addition and subtraction: 1254 + 129 - 967 = 416

So, the result of the expression is 416.
