Judging by the way you write your question, the equation above probably look like this: 5 * (2 - 3) + 4 * 8 + 1
Operations inside a parenthesis goes first
5 * (2 - 3) + 4 * 8 + 1
MDAS rule:
5 * -1 + 4 * 8 + 1
-5 + 32 + 1
-5 + 33
28
or if you mean 5(2 -3) + 4(8 + 1) then,
5(2 -3) + 4(8 + 1)
5(-1) + 4(9)
-5 + 36

here's how I solved it( * stans for multiply): 4*1000+5*100+6*10+1*10+2*110= First you do all the multiplication,and get: 4,000+500+60+10+220= then you add, and the answer is 4790.
1 + 54 + 23 + 23 + 43 = 144
It is: 1/23 times 23 = 1
23
1 + 2 + 1000 + 300 + 23 + 12 = 1338
1 + 1 + 22 = 24
1-14+23=10
346
1*23 = 23
456813
It is: 23-27x when simplified
It is the same as 23+50 = 73
