I don't know your background in economics or mathematics but I can recommend the following books.
For micro I would suggest:
https://www.amazon.com/dp/0324421621/?tag=pfamazon01-20 by Walter Nicholson is arguably the most rigorous micro tb at the undergraduate level. It's typically used in intermediate micro.
https://www.amazon.com/dp/0393957357/?tag=pfamazon01-20 by Hal Varian is the next level up. Typically used in upper undergraduate or masters level. Econ Grads often refer to this book for intuition (which could be said the same for Nicholsons book as well).
If you're feeling really gung-ho
https://www.amazon.com/dp/0195073401/?tag=pfamazon01-20 by Mas-Colell et al. is the bible at first year grad econ.
For the sake of completeness I would also recommend Greg Mankiws 'Principle of Microeconomics' (any edition will do including the first one) and Paul Samuelsons 'Economics' (first edition or one of the earlier editions only). Greg Mankiws book is the dominant first year tb and should be referred to to learn basic concepts. Samuelsons book is a classic and I recommend it for demagogue purposes only (hence recommend only his early editions).
For Macro:
'
https://www.amazon.com/dp/0132078295/?tag=pfamazon01-20' by Olivier Blanchard is a good macro tb with a Keynsian flavour (but that's typical. Almost all undergrad is taught with a keynsian flavour). You might not find this at all rigorous since most of it is algebraic manipulation or basic calc. Personally I think this is one of the better intermediate macro tb.
'
https://www.amazon.com/dp/0199210691/?tag=pfamazon01-20' by Heijdra is one I really like. At level of upper undergrad or masters.
For intuition in macro you can refer to Samuelsons book I recommended earlier.
With macro it's hard to recommend tbs just because it's a fairly contentious area within economics. Compared to micro it was fairly easy to recommend since the tbs I recommended are almost all widely used and accepted. Macro is relatively more fragmented. I could recommend some grad level macro tb (specialised in monetary or growth etc.) but I don't think their is any point since you probably couldn't build any intuition with them without the proper foundations.
For whatever it's worth I think it's more ideal to learn the foundations of micro before you go into macro since many of the fundamental concepts are developed in micro (e.g rational choice framework, demand-supply etc.) and also tbh you really can't learn what economics is about without getting a taste for micro. Another thing to keep in mind is you're not learning 'truths' but a framework to decide on your own what you think is true. Though based on the textbooks I've recommended are through the 'neo-classical' framework/methodology (which is the dominant/mainstream one). I'm sure there are econ people who are heterodox inclined (eg. Austrian school) who would fundamentally disagree with the books i recommend but they can always give you their recommendations.
Finally, I know I've recommended some grad level tbs but I'm not a grad (I just really like economics).
