1) If * stands for -, /stands for +, +stands for *, then which of the following is TRUE?
A) 32/14*6+40-8=44.8 14*8/6+40-8=16.8
c) 32*6/14+32-8=9.9 D) 32/6*14+32-8=18.9
just re-write them in normal notation and evaluate
(I will assume that - stays the same)
e.g. last one
wrong notation:
32/6*14+32-8=18.9 ??
proper notation:
32+6-14*32-8= -418
To solve this question, you need to replace each mathematical symbol with the new symbol according to the given substitutions.
In this case:
* stands for -
/ stands for +
+ stands for *
Now let's solve each option and see which one is true.
A) 32/14*6+40-8 = 44.8
Replace * with -, / with +, and + with *
32/14+6*40-8 = 44.8
2.28+240-8 = 44.8
234.28 = 44.8
So, A is not true.
B) 14*8/6+40-8 = 16.8
Replace * with -, / with +, and + with *
14+8-6+40-8 = 16.8
That simplifies to:
54 = 16.8
So, B is not true.
C) 32*6/14+32-8 = 9.9
Replace * with -, / with +, and + with *
32+6+14+32-8 = 9.9
That simplifies to:
76 = 9.9
So, C is not true.
D) 32/6*14+32-8 = 18.9
Replace * with -, / with +, and + with *
32*6+14+32-8 = 18.9
That simplifies to:
200+14+32-8 = 18.9
238 = 18.9
So, D is not true.
None of the options provided are true when substituting the given symbols for the mathematical operations.
